Allison Stewart of The Washington Post placed the ballad at number one on her list of the Special Year-End Best-of Edition, writing that Beyoncé "just kills this otherwise unremarkable ballad. Her obvious pride in her abilities, in her Beyonce-ness, informs every note, but it doesn't seem showoff-y. It's just sweet." On The Village Voice's 2011 year-end Pazz & Jop singles list, "1+1" was ranked at number 77. The staff members of Pitchfork placed the "1+1" at number 26 on their list of The Top 100 Tracks of 2011, writing:


1+1 (song), Critical reception, Recognition
Following Beyoncé's work on "1+1" is like a journey to the center of her craft, a stripping away of every distraction until all that's left is her voice. Without it, "1+1" would be a muted ballad: Its simple guitar line and stardust-sprinkled strings serve no purpose other than to evoke a sense of familiar romantic intimacy, and then to elegantly step aside while Beyoncé delivers one of her most wonderfully impassioned performances ever.


1+1 (song), Critical reception, Recognition
"1+1" possesses that slightly scary intensity that has been R&B's worst-kept secret weapon since Whitney Houston's "I Have Nothing", but it also demonstrates perfectly how Beyoncé stands apart from every other big-chested diva getting her Whitney on. She lets the song sing through her with a clarity that is never clinical, a strength that never sabotages, and an expressiveness that is precisely as sentimental as its subject matter requires. Beyoncé is R&B's field marshal, demanding of her listeners and herself an absolute fidelity to the music's emotional possibilities, with a perfectly modulated vehemence that is as captivating as it is tyrannical.

In 2019, the same publication listed 1+1 at number 157 on their greatest songs of the decade (2010s) list.

Writing for The New Yorker, Jody Rosen credited the jarring timbral and tonal variations on the song for giving a new musical sound that didn't exist in the world before Beyoncé. He further wrote, "If they sound 'normal' now, it's because Beyoncé, and her many followers, have retrained our ears."

1+1 (song), Music video, Background and synopsis
It was reported in early August 2011 that Beyoncé was recording new music videos for several songs from 4, including "1+1" which was shot by August 3, 2011. The video premiered on August 26, 2011 on  E! News at 7:00 pm EST/PST and it was posted on Beyoncé's website one hour later. It was directed by Beyoncé herself, alongside Lauren Briet and Ed Burke. The video was described by her official website as "the story of love at its best. It's about commitment and fulfillment and it's Beyoncé at her most beautiful. The video experiments with psychedelic visual effects and innovative lighting that gives the clip a cinematic feel." The music video for the song is four and a half minutes long. The director's cut of "1+1" was released on November 1, 2011. It features slightly different scenes to the original.


1+1 (song), Music video, Background and synopsis
The song's video features close-up shots of Beyoncé and incorporates psychedelic light effects and symmetrical filming photography. As the acoustic guitar begins playing, Beyoncé's face comes into view. She stands with her blond hair draped just below her exposed shoulders. As she intently stares into the camera, her skin glistens as though it has been coated with a honey-like and glittery substance. Turning her head from right to left, with her eyes fixed off-camera, Beyoncé starts belting out the first verse. As the chorus is reached, scenes of Beyoncé in a darkened room are shown. Additionally, she places her face delicately against dripping water, gently brushing it with her lips and palms. The scenery changes and Beyoncé is back in the darkened chamber, where she removes her dress.


1+1 (song), Music video, Background and synopsis
A quick shot of the "IV" tattoo inked on Beyoncé's left ring finger is shown (a reference to her album's title, 4), before she bathes in a tub of flowers as well as  berries and blows billows of smoke. As she continues to caress her upper-body, an array of light imagery is projected behind her, serving as a backdrop. During the second verse, the video begins to use symmetrical visual arts. Beyoncé appears standing in front of a purple background, draped by large and billowing garments.


1+1 (song), Music video, Background and synopsis
As the song progresses, her emotions are heightened; zoomed shots of tears trickling down her cheeks are shown. A man appears behind Beyoncé and begins closely embracing her in endearment. The man is nondescript, and his muscular arms grip Beyoncé's body before taking her through a series of dips and bends, while he remains mostly in the background. With tears still rolling down her cheeks, Beyoncé chants to her love interest to make love to her on the song's vocal finale. As the guitar melodies close the song, Beyoncé is seen engulfed by the colorful light and special effects. The video ends with the camera returning to a glistening Beyoncé with blackened scenery in the background.


1+1 (song), Music video, Reception
Jennifer Cady of E! News found the video "sexy" and "pretty stripped down", further writing: "There are no catchy choreographed dances or freakum dresses, just Queen Bey looking gorgeous in lingerie and belting out her love and devotion to her man." Cady added that the video was entertaining because of Beyoncé "seriously magical hair" and her skin, which was sparkling like Edward Cullen. Tanner Stransky of Entertainment Weekly concluded that although the video was different from the previous "heavily produced spectacles" Beyoncé has made, "it's hard to take your eyes off it".


1+1 (song), Music video, Reception
Spencer Kornhaber of The Atlantic criticized the sex appeal which was used in the videos for Lady Gaga's "You and I" (2011) and Katy Perry's "Last Friday Night (T.G.I.F.)" (2011) but felt that "Beyonce's game is unique in its reliance on pure visual magnetism". He wrote that even when Beyoncé is "inhabiting apocalyptic warzones or Mad Men-era domestic scenes", she is always classical. Kornhaber concluded that the video for "1+1" is "catchy, fun dance, pretty face, pretty body", which according to him, is what "Beyonce [has] always been about". Melinda Newman from the website HitFix found "some lovely kaleidoscopic shots and billowing sheets". She added that "we never see her '+1' other than an arm and back shot, but that works to the video's advantage".


1+1 (song), Music video, Reception
Similarly, Willa Paskin of New York magazine praised the final minute of the video in which "we are treated to what is supposed to be the instrumental equivalent of an orgasm", illustrated by split-screen kaleidoscope effects and capped off by Beyoncé staring into the camera "in postcoital contentment". Mawuse Ziegbe of The Boston Globe noted that Beyoncé'ss sex appeal was at its maximum in the video for "1+1".


1+1 (song), Music video, Reception
She compared the kaleidoscope effects with Lady Gaga's "Born This Way" (2011) and finished her review by writing, "ultimately, the clip shows the diva doesn't need the elaborate costumes, club-anthem rhythms and booty-quivering grooves to bring the heat. But a lustrous, fling-ready mane is always handy." Similarly, a writer for MTV UK praised the video's "light effects and symmetrical camera tricks" which "[sell] sex as art". Leah Collins of the Canadian magazine Dose commented that Beyoncé was "gifted with seemingly supernatural powers of hotness" in the video.


1+1 (song), Music video, Reception
A writer for Rolling Stone found the video for "1+1" to be "the moistest music video ever made", adding that it "perfectly matches the sultry, romantic tone of the song". Maura Johnston of The Village Voice found a "'What D'Angelo's 'Untitled (How Does It Feel)' Feels Like For A Girl' vibe" in the video for "1+1" and compared it to the one for "Sweet Dreams" (2009).


1+1 (song), Music video, Reception
Rob Markman of MTV News wrote that the choreography is very different from the Beyoncé's standard dance routines, which feature high-powered steps, swaying hips and "her patented bootylicious shake". He commented, "Instead, Beyoncé settles for ballet-style steps, moving in a leotard and long, flowing cape." Markman added that the video will most likely remain "under the radar" in comparison to the highlights in her high-budgeted reel, which includes clips like "Single Ladies (Put a Ring on It)" (2008) and "Crazy in Love" (2003).


1+1 (song), Music video, Reception
He concluded that "much like the song, the visuals for '1+1' shouldn't be measured in terms of size, but rather in emotive presentation and subdued sexiness". A writer for The Huffington Post wrote that the music video for "Single Ladies (Put a Ring on It)" was Beyoncé'ss most iconic visual work, but added that after the premiere of the video for "1+1", "it may now have company". David Malitz of The Washington Post stated that Beyoncé looks like Hurricane Irene at the beginning of the video, but added that she looks like "any number of chillwave videos" at the end. A more mixed review was given by OK! magazine, which described the video as cheesy. L Magazine's Mike Conklin was unsatisfied with the video, writing that since Beyoncé is rightfully considered to be among "the absolute best [artists]", she can do better."


1+1 (song), Live performances
Beyoncé first performed "1+1" live on American Idol on May 25, 2011. Wearing a purple gown, she sang the song surrounded by smoke and red lighting, declaring, "This is my favorite song". Towards the end of the performance, she fell to her knees and shook the hands of audience members. The performance earned her a standing ovation from the judges and members of the crowd. A writer from The Huffington Post called it "an epic, emotionally-charged performance" and praised the fact that Beyoncé "channel[led] every particle of the room's energy into her lung-bursting calls and cries." Jillian Mapes of Billboard magazine noted, "The sheer force of the ballad literally brought [Beyoncé] to her knees during the performance."

You've been right in front of greatness so often that you need to step back and see it again for the first time." In 2013, John Boone and Jennifer Cady of E! Online placed the video at number eight on their list of Beyoncé's ten best videos, writing that she sounds "perfect". While reviewing 4, Pitchfork's Ryan Dombal complimented the video, writing:


1+1 (song), Live performances
"One of the year's best music videos was directed by Jay-Z and cost about zero dollars to make. The video has a similar impromptu charm to the many intimate, one-shot performance clips popularized by Vincent Moon's Take-Away Shows, its appeal compounded by the shock of seeing such a notoriously manicured superstar without embellishment. It's all quite endearing and personal – two words one might not often associate with this superhumanly talented and famous couple."

Tris McCall of New Jersey On-Line complimented the "magnificent run through the slow-burning" song. Ben Ratliff of The New York Times mentioned "1+1" in the "almost continuous high point" of the concert.

1+2=Paradise
Because of the sexual content the series was one of the manga placed on "Harmful manga" lists by local and national governmental agencies. The negative publicity resulted in Kodansha discontinuing the series.


1+2=Paradise, Plot
The story focuses on Yusuke Yamamoto, the teenage son of two gynaecologists. As a boy, he was almost castrated by his two childhood friends, the twin sisters Yuka and Rika Nakamura, his neighbours, which is why he is afraid of women. Also as a child, he saved the twins from an attacking dog. They grow up with a dream that turns Yusuke's life upside down. At the beginning of the story, they re-appear at the home of Yusuke. His father invites the young women in, to live with them, hoping they will heal his son's gynophobia. The therapeutic benefits of this intended treatment are not entirely clear from the series of, sexually tinted, events that unfold.


1+2=Paradise, Manga
The manga was serialized in Monthly Shōnen Magazine, published by Kodansha, from 1988 to 1990 but discontinued after it met opposition due to the depiction of nudity and sexually tinted content. The manga was re-released by Shōbunkan in 1994 to 1995.


1+2=Paradise, Characters
The elder twin who keeps her hair down, and is more modest and reserved.


1+2=Paradise, Characters
The younger twin who keeps her hair in a ponytail, she is more playful and is more direct and shamelessly presents herself to Yuusuke in lewd situations.


1+2=Paradise, Reception
In a preview for the, February 23, 1990, release of the OVA, the reviewer for the January 1990 issue of Animage magazine notes that 24 year old Kamimura's popular manga is a little naughty but that the female creator has also attracted a loyal fan base among women despite its erotic content.


1+2=Paradise, Reception
Writing a review for Asian Trash Cinema, Jim McLennan observed about the first part of the video adaptation: "The delight of this episode is its sheer, unrelenting, cheerful tackiness. Yes the girls are utter airheads but charges of sexism must be partly countered by the fact that the original manga was created by a woman, Junko Uemura. In addition, Yusuke is just as socially inadequate in his way, which is doubly amusing given that he is a parody of the likely intended target audience."


1+9+8+2
1+9+8+2 (official title in other sources as 1982), is the fifteenth studio album by the English rock band Status Quo, released on 16 April 1982. It was the first to include new drummer Pete Kircher, who had recently replaced John Coghlan, and also the first to credit keyboard player Andy Bown as a full member of the band; on the previous few releases he had merely been listed as a guest musician although he had long been an integral member in all but name.


1+9+8+2
Its release came shortly before the band appeared at a concert at the National Exhibition Centre, Birmingham, in the presence of the Prince of Wales, and the resulting publicity probably helped to send it to an entry position of No. 1 in the album chart, making it their fourth and last No. 1 album. Nevertheless, it received a lukewarm reception from fans. "Dear John", the first single and the only track not written by any of the band, reached No. 10 in the UK, but "She Don't Fool Me" stalled at No. 36.


1+9+8+2
1982 was the 20th anniversary of band members Francis Rossi and Alan Lancaster first meeting each other, and the sum of the numbers 1+9+8+2 is 20 (shown as the Roman numerals 'XX' underneath the album title), hence the name of the album.

It peaked within the top 10 of the charts in several countries worldwide, including Germany, New Zealand and the United Kingdom. The song is heavily inspired by 1980s electro music production.


1, 2 Step
Throughout the song, Ciara gives a description of how the song's beat feels as she exhorts party-goers to dance to the music. "1, 2 Step" was ranked 59th on Billboard's Top 100 Songs of the 2000s.

Pha asked Missy Elliott to appear on the track and she accepted. Elliott recorded her rap verse at the Hit Factory Criteria in Miami.


1, 2 Step, Background and composition
"1, 2 Step" is a Crunk&B track, which is strongly influenced by 1980s electro music. The song was created on one of Jazze Pha's five Akai MPC3000s. Pha used laser pulses from E-mu Proteus in the 2000s that were used for old school hip hop songs and b-boy break dance tracks. "1, 2 Step" is inspired by Afrika Bambaataa's "Planet Rock." Jazze Pha thought about how he could create a more melodic version and "shared some interesting ideas on what kind of music he would like to produce with her. Let's put it this way, it would be epic." "1, 2 Step" references her past song "Goodies" and "We Will Rock You" by Queen.

Slant thought that "1, 2 Step" was a "fun dance track."

It also includes a vocal sample from "Wikka Wrap" by the Evasions, from 1981. The main riff is from "Good Times" by Chic, from 1979.

1, 2, 3, 4 (Sumpin' New), Critical reception
Ralph Tee from Music Week's RM Dance Update rated the song four out of five. He added, "Unlike so many hip hop singles which lean towards often depressing issues, this is a spirited happy record about having a great party. It kicks off with a sample from The Evasions' 1981 novelty hit 'Wikka Wrap', the Alan Whicker impersonation leading towards an upbeat disco rap which utilises the much-used Chic bassline from 'Good Times' and some sampled Tom Browne horns. A strong third single from the hottest rapper in the biz right now." Another editor, James Hamilton deemed it a "ultra infectious jiggly rap smacker".


1, 2, 3, 4 (Sumpin' New), Music video
A music video (directed by David Dobkin) for the Timber mix was released, featuring Coolio attempting to get to a party. Jamie Foxx and A.J. Johnson are also in the music video.

The title song written by Sal Trimachi and Bobbi Trimachi, was the albums' only hit single for the band, peaking at #5 on the Billboard Hot 100, with both the album and the single just barely missing the success of their first release.


1, 2, 3, Red Light
As with their previous album there has been questions about who played what. Original drummer Floyd Marcus has stated that he still played on the records even when a new drummer, Rusty Oppenheimer, was brought in. This does not seem to be the case for this album, as Oppenheimer receives a writing credit on the album but also does not perform on it as Marcus has explained that a number of session musicians were brought in to record new backing tracks for Mark Gutkowski to sing over while the band was out touring. This is supported by former Super K Productions staff writer and producer, Steve Dworkin, who, in an email to Unofficial 1910 Fruitgum Company Home Page creator Jonathan Gatarz, has listed the names of the session musicians.

1,000 Grams
1,000 Grams, Vol. 1 is a mix-tape by the rap artist Jeezy hosted by DJ Scream. It was released on August 12, 2010.


1,000 Grams, Background
The mixtape has Jeezy rapping over samples of some of the most popular hip hop beats of 2010. The first track to be leaked from 1,000 Grams, was "Death B4 Dishonor", in which Jeezy samples Rick Ross' hit single "B.M.F. (Blowin' Money Fast)". On the track, Jeezy appears to be criticising Rick Ross by saying "How you blowin' money fast, you don't know the crew / Oh you're part of the fam, shit I never knew." However, in an interview with MTV, Jeezy claimed it was not a criticism and that the line was not aimed at anyone in particular.


1,000 Grams, Background
DJ Scream hosts this mixtape and has many tags on it; a tagless (or no DJ) version of the mixtape has also been released. This is volume one of what appeared to be a new series by Jeezy, but so far there have been no official statements on when volume 2 will be released.


1,000 Grams, Critical reception
Pitchfork's Tom Breihan wrote that the mixtape "seems to exist to support his opening salvo against Ross. And judging by the respective quality of both this tape and Ross' great new Teflon Don, Jeezy is heading for a big L here." David Malitz of The Washington Post called Jeezy's rhymes "cheaply glorifying" and the backing tracks "predictable". Sam Hockley-Smith of The Fader said that while most mixtapes in which the artist raps over other people's songs consist of "watered down versions of the original" tracks, Jeezy on this mixtape is "always stable. Never really varying in tempo too much, just working with any beat that gets thrown his way. It’s a pretty sweet example of why this guy has outlasted a lot of his peers."

1,000 Hours, Album information
“1,000 Hours” was written by Billie Joe about his best friend's sister, Jennifer, who he was romantically interested in. Jennifer didn't want to put up with a younger and inexperienced guy, and Billie Joe wrote about his experience in a song.


1,000 Hours, Album information
“Dry Ice” is a similar song. He is deeply in love with a girl, and keeps dreaming of her, but he doesn't know if she feels the same way. He writes this song as a "letter" to that girl, who he hopes will eventually read it.


1,000 Hours, Album information
“Only of You” is a song about love at first sight. The narrator loses sleep because of this person he is so infatuated with. He's only seen them once, but it was enough to cause these love-filled thoughts to take over him. They are only friends and he doesn't dare tell them his inside thoughts - all he can do is hope that this wonderful infatuation never ends.


1,000 Hours, Album information
“The One I Want” is most likely another song inspired by the author's feelings towards his best friend's sister. In this song he mentions that she already knows how he feels about her, and so he's wondering why they are still not together and finds no reasons - she made him feel this way, and now she's the only one that he wants. He believes that this love he feels towards this girl will never end.


1,000 Hours, Album information
The 1,000 Hours EP was included on the compilation album 1,039/Smoothed Out Slappy Hours, which includes Green Day's debut LP 39/Smooth, as well as their 1990 EP Slappy. It has also been back in print on vinyl since 2009, with the reissue of 39/Smooth on vinyl.

1,000 Years
1,000 Years is the first album by The Corin Tucker Band, released on October 5, 2010, and the first album Tucker released since Sleater-Kinney went on "hiatus" in 2006. She recorded the album along with Seth Lorinczi and Julianna Bright of both Golden Bears and Circus Lupus, as well as Sara Lund of Hungry Ghost and Unwound. Lorinzci was also the album's producer. The only single released from 1,000 Years was "Doubt".


1,000 Years
The album received generally positive reviews from critics, many of whom noted that the album was stylistically much more muted and intimate than her work with Sleater-Kinney. As of August 2012, the album has sold about 8,000 copies. It peaked at #9 on the Top Heatseekers Chart, and at #49 on the Top Independent Albums Chart, both on October 23, 2010.


1,000 Years, Background and recording
Tucker told The Portland Mercury that she was recording the album in April 2010, and said it was "definitely more of a middle-aged mom record, in a way. It's not a record that a young person would write." The origins of these songs lie in material Tucker wrote for live performances in early 2009 in Portland, after which many people encouraged her to make her own album. Tucker said that she wanted to create something both quiet and powerful in the making of this album.


1,000 Years, Background and recording
Tucker feels that Seth Lorinczi lent the album many of its creative ideas, and has stated, "He brought so many amazing ideas to the songs, it was an entirely new foray." Some of the album's tracks were written initially for the Twilight: New Moon soundtrack. The songs in question include closer "Miles Away".


1,000 Years, Production
Some critics described Seth Lorinczi's production on 1,000 Years as lo-fi, with Slant noting a lack of refinement in the production, especially on "Doubt" and "Dragon". Tucker, in an interview with The Aquarian Weekly, wrote that Lorinzci's approach to production was to "make each song complete sonically," adding that, in her new project, she was trying to build on her past role as a member of Sleater-Kinney.


1,000 Years, Composition, Music
Tucker said that her influences for this album included The Lion and the Cobra, as well as The Slits, The Raincoats, and The English Beat. She also named Patti Smith, Chrissie Hynde and Sinead O’Connor as influences in an interview with PopMatters. Tucker's singing on the album is much more subdued and intimate than it was on her work with Sleater-Kinney, when her voice was distinctive for its strong, surging sound. However, she occasionally returns to the full force of her "banshee" voice for which she was previously well-known, for example on "Riley".


1,000 Years, Composition, Music
1,000 Years has been compared, both favorably and unfavorably, to Tucker's work with Sleater-Kinney, with the general conclusion being that the album's style differs significantly from that of Sleater-Kinney. For example, Pitchfork Media wrote that “fans jonesing for a Sleater-Kinney fix will be disappointed.” Rolling Stone and Drowned in Sound noted the increased usage of piano and cello, among other instruments, on this album as opposed to in Sleater-Kinney's music. DiS singled out the organ on ‘Handed Love’ as well as the military rhythm of 'Half a World Away' as examples of this.


1,000 Years, Composition, Lyrics
It has been noted that Tucker's marriage seems to have influenced the album's lyrics, in particular those of "Half a World Away" and "It's Always Summer." Regarding the album's lyrics, Ann Powers of the Los Angeles Times wrote that they discuss the process of coming to recognize changes in one's reality and surroundings.


1,000 Years, Tour
Tucker toured on both U.S. coasts to support the 1,000 Years album, in addition to dates in other parts of the country. Additionally, on May 3, 2011, Corin opened for M. Ward at the Crystal Ballroom, in Portland, Oregon. In a Kill Rock Stars press release, Tucker stated that she was no longer able to tour for as long as she once could, and that "We’re definitely playing shows, but it’s more like a week here, a week there."


1,000 Years, Reception
The album received mostly positive reviews; on Metacritic its weighted average is 76 out of 100, indicating "generally favorable reviews." The most positive review was from Robert Christgau, who gave it an A and called it "A deep, pained, sober, subtle album". In addition to giving the album an A, Christgau ranked 1,000 Years as the 11th best album of 2010 in his year-end list. This contrasted starkly with the most negative review, a C+ from EW's Whitney Pastorek, who said that, on the album,


1,000 Years, Reception
Corin Tucker's voice — always so uniquely emotive in the punkier contexts of S-K — looms uncomfortably over songs that sound scrapbooked from other '90s-centric acts (Liz Phair, Pavement) but never take on a form of their own.


1,000 Years, Reception
With regard to the album's only single "Doubt," Adam Kivel of Consequence of Sound praised the song on the basis that Tucker's characteristic "howl" made a return on the track. Similarly, Thom Gibbs of Drowned in Sound praised the song because it features Tucker in more familiar vocal form. Kivel also noted that the song was stripped down and lacked the same wild energy as Sleater-Kinney's music. Kivel also compared the sound of "Thrift Store Coats" to that of the Fiery Furnaces, and described "Dragon" as "dramatic" while noting that it was dominated by cello.


1,000 Years, Commercial performance
As of August 2012, 1,000 Years had sold about 8,000 copies.


1,000 first-class runs before the end of May
A batsman has scored 1,000 first-class runs before the end of May in an English cricket season on only eight occasions. In five of these occasions, the batsman reached 1,000 runs with innings played in April and May, but three scored 1,000 runs in the month of May alone. These were: W.G. Grace in 1895, Wally Hammond in 1927, and most recently Charlie Hallows in 1928.


1,000 first-class runs before the end of May
Donald Bradman is the only person to have scored 1,000 runs before the end of May twice, in 1930 and 1938. Uniquely, a second batsman also reached 1,000 runs before the end of May in 1938, Bill Edrich, mainly thanks to a sporting declaration by Australia at 5.09pm on the third and final day of the match against Middlesex at Lord's on 28–30 May, when Edrich needed another 10 runs.


1,000 first-class runs before the end of May
The rarely-achieved feat has become even more scarce since the Second World War, with only Glenn Turner and Graeme Hick reaching 1,000 runs before the end of May since 1938. In part, this is due to the reduced schedule of first-class cricket since the introduction of domestic one-day cricket competitions in the 1970s, and a corresponding reduction in the number of first-class matches played by English county teams and touring international teams.


1,000 first-class runs before the end of May
The start of the English cricket season has crept earlier in April in recent years, and Nick Compton came close to achieving 1,000 runs before the end of May 2012, needing 59 runs on 31 May against Worcestershire. Rain intervened with Compton having only scored nine, but he scored a century after resuming his innings the following day to pass 1,000 runs on 1 June. Other near misses include John Langridge who reached 1,000 runs on 2 June 1949, and Brian Lara, who reached 1,000 runs on 2 June 1994 from just seven innings.


1,000,000
One million (1,000,000), or one thousand thousand, is the natural number following 999,999 and preceding 1,000,001. The word is derived from the early Italian millione (milione in modern Italian), from mille, "thousand", plus the augmentative suffix -one. It is commonly abbreviated in British English as m (not to be confused with the metric prefix m (milli-) for 1×10−3), M, MM ("thousand thousands", from Latin "Mille"; not to be confused with the Roman numeral MM = 2,000), mm, or mn in financial contexts.


1,000,000
In scientific notation, it is written as 1×106 or 106. Physical quantities can also be expressed using the SI prefix mega (M), when dealing with SI units; for example, 1 megawatt (1 MW) equals 1,000,000 watts.


1,000,000
The meaning of the word "million" is common to the short scale and long scale numbering systems, unlike the larger numbers, which have different names in the two systems.


1,000,000
The million is sometimes used in the English language as a metaphor for a very large number, as in "Not in a million years" and "You're one in a million", or a hyperbole, as in "I've walked a million miles" and "You've asked a million-dollar question".


1,000,000
1,000,000 is also the square of 1000 and also the cube of 100.


1,000,000, Visualizing one million
Even though it is often stressed that counting to precisely a million would be an exceedingly tedious task due to the time and concentration required, there are many ways to bring the number "down to size" in approximate quantities, ignoring irregularities or packing effects.


1,000,000, Visualizing one million
In Indian English and Pakistani English, it is also expressed as 10 lakh. Lakh is derived from lakṣa for 100,000 in Sanskrit.


1,000,000,000
1,000,000,000 (one billion, short scale; one thousand million or milliard, yard, long scale) is the natural number following 999,999,999 and preceding 1,000,000,001. One billion can also be written as b or bn.


1,000,000,000
In standard form, it is written as 1 × 109. The metric prefix giga indicates 1,000,000,000 times the base unit. Its symbol is G.


1,000,000,000
One billion years may be called an eon in astronomy or geology.


1,000,000,000
Previously in British English (but not in American English), the word "billion" referred exclusively to a million millions (1,000,000,000,000). However, this is no longer common, and the word has been used to mean one thousand million (1,000,000,000) for several decades.


1,000,000,000
The term milliard can also be used to refer to 1,000,000,000; whereas "milliard" is rarely used in English, variations on this name often appear in other languages.


1,000,000,000
In the South Asian numbering system, it is known as 100 crore or 1 arab.


1,000,000,000, Sense of scale
The facts below give a sense of how large 1,000,000,000 (109) is in the context of time according to current scientific evidence:


1,000,000,000, Sense of scale, Count
A is a cube; B consists of 1000 cubes the size of cube A, C consists of 1000 cubes the size of cube B; and D consists of 1000 cubes the size of cube C. Thus there are 1 million A-sized cubes in C; and 1,000,000,000 A-sized cubes in D.


1,039/Smoothed Out Slappy Hours
1,039/Smoothed Out Slappy Hours is a collection of early recordings by American rock band Green Day, released on October 1, 1991 by Lookout Records. Often erroneously referred to as the band's debut album, the compilation combines the band's actual debut 39/Smooth and its first two extended plays Slappy and 1,000 Hours, which are all currently out of print, hence its name being an amalgamation of the album and the two EPs. The album included one cover, "Knowledge" (originally from the Slappy EP), which was originally by influential California punk band Operation Ivy, whose singer, Jesse Michaels, contributed the artwork for the album. The cover art features the same image from 39/Smooth.


1,039/Smoothed Out Slappy Hours
Lookout! re-released the album in 2004 with special limited packaging and all new enhanced CD-ROM features, including live performances and pictures. The album was re-issued in the same packaging in 2007 through Reprise Records after Green Day pulled the album in August 2005, as well as all of its other material released through the label, from Lookout! due to unpaid royalties. The album has been certified Gold in the U.S. by the RIAA, and according to Nielsen SoundScan, it has sold 632,000 copies in the U.S. as of August 2010. The album was certified Gold in the UK on July 22, 2013, representing sales of at least 100,000. It has sold more than 2 million copies worldwide.


1,039/Smoothed Out Slappy Hours, Release
Initially released in 1991 through Lookout! Records (despite the 1990 copyright date on the album), the label re-issued the album in a remastered form in 2004. It was re-released on CD on January 9, 2007, by Reprise Records, the label Green Day has been signed to since leaving Lookout!. In Europe, the album was already re-released by Epitaph Europe, and has remained in print. It was reissued on vinyl on March 24, 2009, by Reprise in a package containing the original 10-song 39/Smooth LP along with reissues of the 1,000 Hours and Slappy EPs. On the 2009 reissues, the song "I Want to Be Alone" is omitted.


1,039/Smoothed Out Slappy Hours, Reception
Reviews of 1,039/Smoothed Out Slappy Hours were largely mixed; for example, The New Rolling Stone Album Guide gave it 2.5 out of 5 stars. Brad of Punknews.org gave it 3.5 out of 5 stars, writing, "All in all, this album succeeds at being quite good. It shows obvious influences from the Clash and the Ramones, and is a good debut for a young band that would later change the course of Punk Rock forever by opening the floodgates for New School bands."

1,1'-Azobis-1,2,3-triazole
1,1′-Azobis-1,2,3-triazole is a moderately explosive but comparatively stable chemical compound which contains a long continuous chain of nitrogen atoms, with an unbroken chain of eight nitrogen atoms cyclised into two 1,2,3-triazole rings. It is stable up to 194 °C. The compound exhibits cis–trans isomerism at the central azo group: the trans isomer is more stable and is yellow, while the cis isomer is less stable and is blue. The two rings are aromatic and form a conjugated system with the azo linkage. This chromophore allows the trans compound to be isomerised to the cis when treated with an appropriate wavelength of ultraviolet light.


1,1'-Azobis-1,2,3-triazole, Related compounds
In 2011, azobis(tetrazole) was prepared by Klapötke and Piercey which has a ten-nitrogen chain. The record was later taken by a N11 chain compound synthesized by a group of Chinese researchers. A branched chain N11 system has also been reported as part of an unstable but highly nitrogen rich azidotetrazole derivative with formula C2N14.


1,1'-Binaphthyl
1,1'-Binaphthyl is an organic compound with the formula (C10H7)2. It is one of the dimers of naphthalene (or literally: dimers of naphthyl). A colorless solid, it has attracted some attention because the atropisomers can be isolated due in part to hindered rotation between the two naphthyl subunits. The halflife of the racemization is 14.5 min. at 50 °C. Substituted derivatives of this parent species, e.g. binaphthol, exhibit much higher barriers to racemization.


1,1'-Bis(diphenylphosphino)ferrocene
1,1′-Bis(diphenylphosphino)ferrocene, commonly abbreviated dppf, is an organophosphorus compound commonly used as a ligand in homogeneous catalysis. It contains a ferrocene moiety in its backbone, and is related to other bridged diphosphines such as 1,2-bis(diphenylphosphino)ethane (dppe).


1,1'-Bis(diphenylphosphino)ferrocene, Preparation
This compound is commercially available. It may be prepared by treating dilithioferrocene with chlorodiphenylphosphine:


1,1'-Bis(diphenylphosphino)ferrocene, Preparation
The dilithiation of ferrocene is easily achieved with n-butyllithium in the presence of TMEDA. Many related ligands can be made in this way. The Fe center is typically not involved in the behavior of the ligand.


1,1'-Bis(diphenylphosphino)ferrocene, Reactions
Dppf readily forms metal complexes. The palladium derivative, (dppf)PdCl2, which is popular for palladium-catalyzed coupling reactions, is prepared by treating dppf with the acetonitrile or benzonitrile adducts of palladium dichloride: Substitution of the phenyl substituents in dppf leads to derivatives with modified donor-acceptor properties at the phosphorus atoms.


1,1'-Dihydroxydicyclohexyl peroxide
1,1'-Dihydroxydicyclohexyl peroxide is an organic compound with the formula (C6H10OH)2O2. It is one of the peroxides derived from the reaction of cyclohexanone and hydrogen peroxide. Upon treatment with acid and additional peroxide, it converts to the cyclic diperoxide, bis(cyclohexylidene peroxide), (C6H10)2(O2)2.


1,1,1,2,2,3,3-Heptachloropropane
1,1,1,2,2,3,3-Heptachloropropane is a compound of chlorine, hydrogen, and carbon. Its linear formula is C2Cl5CHCl2


1,1,1,2,3,3,3-Heptafluoropropane
1,1,1,2,3,3,3-Heptafluoropropane, also called heptafluoropropane, HFC-227ea (ISO name), HFC-227 or FM200, as well as apaflurane (INN), is a colourless, odourless gaseous halocarbon commonly used as a gaseous fire suppression agent.


1,1,1,2,3,3,3-Heptafluoropropane, Chemistry
Its chemical formula is CF3-CHF-CF3, or C3HF7. With a boiling point of −16.4 °C, it is a gas at room temperature. It is slightly soluble in water (260 mg/L).


1,1,1,2,3,3,3-Heptafluoropropane, Use
HFC-227ea finds use in fire suppression systems in data processing and telecommunication facilities, and in protection of many flammable liquids and gases. HFC-227ea falls in the category of Clean Agents and is governed by NFPA 2001 - Standard for Clean Agent Fire Extinguishing Systems. Effective fire suppression requires introducing a concentration of the HFC-227ea agent between 6.25% and 9% depending on the hazard being suppressed. Its NOAEL for cardiac sensitization is 9%. The United States Environmental Protection Agency allows concentration of 9% volume in occupied spaces without mandated egress time, or up to 10.5% for a limited time. Most fire suppression systems are designed to provide concentration of 6.25-9%.


1,1,1,2,3,3,3-Heptafluoropropane, Use
The HFC-227ea fire suppression agent was the first non-ozone-depleting replacement for Halon 1301. In addition, HFC-227ea leaves no residue on valuable equipment after discharge.


1,1,1,2,3,3,3-Heptafluoropropane, Use
HFC-227ea contains no chlorine or bromine atoms, presenting no ozone depletion effect. Its atmospheric lifetime is approximated between 31 and 42 years. It leaves no residue or oily deposits and can be removed by ventilation of the affected space.


1,1,1,2,3,3,3-Heptafluoropropane, Use
As an aerosol propellant, HFC-227ea is used in pharmaceutical metered dose inhalers such as those used for dispensing asthma medication.


1,1,1,2,3,3,3-Heptafluoropropane, Safety
At high temperatures, heptafluoropropane will decompose and produce hydrogen fluoride. This is observable as presence of sharp, pungent odour, which can be perceived in concentrations far below a dangerous level. Other decomposition products include carbonyl fluoride, carbon monoxide and carbon dioxide. Prior to re-entry of a room where HFC-227ea system has been activated to suppress a fire, the atmosphere should be tested. An  added to heptafluoropropane is able to reduce the amount of hydrogen fluoride. Contact with liquid HFC-227ea may cause frostbite.


1,1,1,2,3,3,3-Heptafluoropropane, Climate change considerations
Heptafluoropropane (HFC-227ea) contributes to climate change. It has a global warming potential (GWP) of 3,220 over 100 years.


1,1,1,2,3,3,3-Heptafluoropropane, Climate change considerations
Due to its high GWP, the HFC-227ea has been included in the list of controlled substances of the Montreal Protocol (2016 Kigali amendment, in effect in January 2019). Under EU regulations, production, imports and sales of HFC-227ea in spray cans such as freeze sprays or dusters have been prohibited since 2014, as the GWP is over the limit of 150 for these applications.


1,1,1,2-Tetrachloroethane
1,1,1,2-Tetrachloroethane is a chlorinated hydrocarbon. It is a colorless liquid with a sweet chloroform-like odor. It is used as a solvent and in the production of wood stains and varnishes.


1,1,1,2-Tetrachloropropane
1,1,1,2-Tetrachloropropane is a compound of chlorine, hydrogen, and carbon. It has chemical formula C3H4Cl4. The structure has a propane skeleton, but four of the hydrogen atoms are replaced by chlorine atoms.


1,1,1,2-Tetrafluoroethane
1,1,1,2-Tetrafluoroethane (also known as norflurane (INN), R-134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential and a lower 100-year global warming potential (1,430, compared to R-12's GWP of 10,900). It has the formula CF3CH2F and a boiling point of −26.3 °C (−15.34 °F) at atmospheric pressure. R-134a cylinders are colored light blue. A phaseout and transition to HFO-1234yf and other refrigerants, with GWPs similar to CO2, began in 2012 within the automotive market.


1,1,1,2-Tetrafluoroethane, Uses
1,1,1,2-Tetrafluoroethane is a non-flammable gas used primarily as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners. These devices began using 1,1,1,2-tetrafluoroethane in the early 1990s as a replacement for the more environmentally harmful R-12. Retrofit kits are available to convert units that were originally R-12-equipped.


1,1,1,2-Tetrafluoroethane, Uses
Other common uses include plastic foam blowing, as a cleaning solvent, a propellant for the delivery of pharmaceuticals (e.g. bronchodilators), wine cork removers, gas dusters ("canned air"), and in air driers for removing the moisture from compressed air. 1,1,1,2-Tetrafluoroethane has also been used to cool computers in some overclocking attempts. It is the refrigerant used in plumbing pipe freeze kits. It is also commonly used as a propellant for airsoft airguns. The gas is often mixed with a silicone-based lubricant.


1,1,1,2-Tetrafluoroethane, Uses, Aspirational and niche applications
1,1,1,2-Tetrafluoroethane is also being considered as an organic solvent suitable for extraction of flavor and fragrance compounds, as a possible alternative to other organic solvents and supercritical carbon dioxide. It can also be used as a solvent in organic chemistry, both in liquid and supercritical fluid. It is used in the resistive plate chamber particle detectors in the Large Hadron Collider. It is also used for other types of particle detectors, e.g. some cryogenic particle detectors. It can be used as an alternative to sulfur hexafluoride in magnesium smelting as a shielding gas.


1,1,1,2-Tetrafluoroethane, Uses, Aspirational and niche applications
1,1,1,2-Tetrafluoroethane is also being considered as an alternative to sulfur hexafluoride as a dielectric gas. Its arc-quenching properties are poor, but its dielectric properties are fairly good.


1,1,1,2-Tetrafluoroethane, History and environmental impacts
1,1,1,2-Tetrafluoroethane was introduced in the early 1990s as a replacement for dichlorodifluoromethane (R-12), which has massive ozone depleting properties. Even though it has insignificant ozone depletion potential (ozone layer) and negligible acidification potential (acid rain), it has a 100-year global warming potential (GWP) of 1430 and an approximate atmospheric lifetime of 14 years. Its concentration in the atmosphere and contribution to radiative forcing have been growing since its introduction. Thus it was included in the IPCC list of greenhouse gases.


1,1,1,2-Tetrafluoroethane, History and environmental impacts
R-134a was consequently banned from use in the European Union, starting with cars in 2011, by a directive of 2006 banning gases in air conditioning systems with a GWP above 100.


1,1,1,2-Tetrafluoroethane, History and environmental impacts
1,1,1,2-tetrafluoroethane is subject to use restrictions in the US and other countries as well. The Society of Automotive Engineers (SAE) has proposed that it be best replaced by a new fluorochemical refrigerant HFO-1234yf (CF3CF=CH2) in automobile air-conditioning systems. By model year 2021, newly manufactured light-duty vehicles in the United States will no longer use R-134a.


1,1,1,2-Tetrafluoroethane, History and environmental impacts
California may also prohibit the sale of canned R-134a to individuals to avoid non-professional recharge of air conditioners. A ban had been in place in Wisconsin since October 1994 under ATCP 136 prohibiting sales of container sizes holding less than 15 lbs of 1,1,1,2-tetrafluoroethane, but this restriction applied only when the chemical was intended to be a refrigerant. However, the ban was lifted in Wisconsin in 2012. During the time that it was active, this Wisconsin-specific ban contained loopholes. For example, it was legal for a person to purchase gas duster containers with any amount of the chemical because in that instance the chemical is neither intended to be a refrigerant  nor is HFC-134a included in the § 7671a listing of class I and class II substances.


1,1,1,2-Tetrafluoroethane, Production and reactions
Tetrafluoroethane is typically made by reacting trichloroethylene with hydrogen fluoride:


1,1,1,2-Tetrafluoroethane, Safety
Mixtures with air of the gas 1,1,1,2-tetrafluoroethane are not flammable at atmospheric pressure and temperatures up to 100 °C (212 °F). However, mixtures with high concentrations of air at elevated pressure and/or temperature can be ignited. Contact of 1,1,1,2-tetrafluoroethane with flames or hot surfaces in excess of 250 °C (482 °F) may cause vapor decomposition and the emission of toxic gases including hydrogen fluoride and carbonyl fluoride, however the decomposition temperature has been reported as above 370 °C,. 1,1,1,2-Tetrafluoroethane itself has an LD50 of 1,500 g/m3 in rats, making it relatively non-toxic, apart from the dangers inherent to inhalant abuse. Its gaseous form is denser than air and will displace air in the lungs. This can result in asphyxiation if excessively inhaled. This contributes to most deaths by inhalant abuse.


1,1,1,2-Tetrafluoroethane, Safety
Aerosol cans containing 1,1,1,2-tetrafluoroethane, when inverted, become effective freeze sprays. Under pressure, 1,1,1,2-tetrafluoroethane is compressed into a liquid, which upon vaporization absorbs a significant amount of thermal energy. As a result, it will greatly lower the temperature of any object it contacts as it evaporates.


1,1,1,2-Tetrafluoroethane, Medical use
For its medical uses, 1,1,1,2-tetrafluoroethane has the generic name norflurane. It is used as propellant for some metered dose inhalers. It is considered safe for this use. In combination with pentafluoropropane, it is used as a topical vapocoolant spray for numbing boils before curettage. It has also been studied as a potential inhalational anesthetic, but it is nonanaesthetic at doses used in inhalers.

1,1,1,3,3,3-Hexachloropropane
1,1,1,3,3,3-Hexachloropropane is a compound of chlorine, hydrogen, and carbon, with chemical formula C3Cl6H2, specifically Cl3C−CH2−CCl3. Its molecule can be described as that of propane with chlorine atoms substituted for the six hydrogen atoms on the extremal carbons.


1,1,1,3,3,3-Hexachloropropane, History and properties
There are 29 chlorinated derivatives of propane (four of them being hexachloropropanes, with the formula C3Cl6H2). This was the last one of them to be synthesized—by A. W. Davis and A. M. Whaley—in 1950.


1,1,1,3,3,3-Hexachloropropane, History and properties
1,1,1,3,3,3-Hexachloropropane is a liquid that boils at 206 °C. Its boiling point is significantly higher than expected based on estimations from various molecular parameters.


1,1,1,3,3,3-Hexachloropropane, Production
The original synthesis by Davis and Whaley obtained the compound by reacting 1,1,3,3-tetrachloropropane and/or 1,1,1,3-tetrachloropropane with chlorine at 80-100 °C, through 1,1,1,3,3-pentachloropropane as an intermediate step.


1,1,1,3,3,3-Hexachloropropane, Production
The compound can be produced quantitatively also by reacting carbon tetrachloride CCl4 and 1,1-dichloroethene Cl2C=CH2 at 80-150 °C, with a copper-based catalyst, such as copper(I) chloride or copper(II) chloride, and possibly an amine as co-catalyst. The same process can generate higher chlorinated alkanes of the form H3C−(CH2−CCl2)nCl.

1,1,1,3,3,3-Hexafluoropropane
When used as a fire suppressant, hexafluoropropane carries the DuPont trade name, FE-36.


1,1,1,3,3,3-Hexafluoropropane
1,1,1,3,3,3-Hexafluoropropane is a greenhouse gas; its global warming potential is 9810.


1,1,1,3,3,3-Hexafluoropropane

1,1,1-Trichloro-2,2,2-trifluoroethane
Trichlorotrifluoroethane, also called 1,1,1-Trichloro-2,2,2-trifluoroethane or CFC-113a is a chlorofluorocarbon (CFC). It has the formula Cl3C2F3.


1,1,1-Trichloro-2,2,2-trifluoroethane, Environmental effects
A team of researchers at the University of East Anglia analysed unpolluted air samples from Tasmania dating from the period 1978 to 2012. They concluded that the CFC's they studied had started entering the atmosphere from anthropogenic sources in the 1960s and that while the abundance of certain CFCs had decreased, owing to the Montreal Protocol, the abundance of CFC-113a in the atmosphere was still growing. Its source remained uncertain, but production of hydrofluorocarbons in East Asia was suspected by some. Between 2012 and 2017, concentrations of the gas jumped by 40 percent.


1,1,1-Trichloroacetone
1,1,1 -Trichloroacetone is a chlorinated analogue of acetone with the chemical formula CH3COCCl3. It is a colourless liquid. 1,1,1 -Trichloroacetone can be synthesised from chlorination of chloroacetone (1,1,3-trichloroacetone is formed as a by-product). An alternative synthesis involves the transfer of a trichloromethyl group from trichloroacetate onto acetyl chloride.


1,1,1-Trichloroethane
The organic compound 1,1,1-trichloroethane, also known as methyl chloroform, is a chloroalkane. This colorless, sweet-smelling liquid was once produced industrially in large quantities for use as a solvent. It is regulated by the Montreal Protocol as an ozone-depleting substance and its use is being rapidly phased out.


1,1,1-Trichloroethane, Production
1,1,1 -Trichloroethane was first reported by Henri Victor Regnault in 1840. Industrially, it is usually produced in a two-step process from vinyl chloride. In the first step, vinyl chloride reacts with hydrogen chloride at 20-50 °C to produce 1,1-dichloroethane:


1,1,1-Trichloroethane, Production
This reaction is catalyzed by a variety of Lewis acids, mainly aluminium chloride, iron(III) chloride, or zinc chloride. The 1,1-dichloroethane is then converted to 1,1,1-trichloroethane by reaction with chlorine under ultraviolet irradiation:


1,1,1-Trichloroethane, Production
This reaction proceeds at 80-90% yield, and the hydrogen chloride byproduct can be recycled to the first step in the process. The major side-product is the related compound 1,1,2-trichloroethane, from which the 1,1,1-trichloroethane can be separated by distillation.


1,1,1-Trichloroethane, Production
A somewhat smaller amount of 1,1,1-trichloroethane is produced from the reaction of 1,1-dichloroethene and hydrogen chloride in the presence of an iron(III) chloride catalyst:


1,1,1-Trichloroethane, Production
1,1,1 -Trichloroethane is sold with stabilizers because it is unstable with respect to dehydrochlorination and attacks some metals. Stabilizers comprise up to 8% of the formulation, including acid scavengers (epoxides, amines) and complexants.


1,1,1-Trichloroethane, Uses
1,1,1 -Trichloroethane is generally considered a non-polar solvent. Owing to the good polarizability of the chlorine atoms, it is a superior solvent for organic compounds that do not dissolve well in hydrocarbons such as hexane. It is an excellent solvent for many organic materials and also one of the least toxic of the chlorinated hydrocarbons. Prior to the Montreal Protocol, it was widely used for cleaning metal parts and circuit boards, as a photoresist solvent in the electronics industry, as an aerosol propellant, as a cutting fluid additive, and as a solvent for inks, paints, adhesives, and other coatings. 1,1,1 -Trichloroethane is also used as an insecticidal fumigant.


1,1,1-Trichloroethane, Uses
It was also the standard cleaner for photographic film (movie/slide/negatives, etc.). Other commonly available solvents damage emulsion, and thus are not suitable for this application. The standard replacement, Forane 141 is much less effective, and tends to leave a residue. 1,1,1 -Trichloroethane was used as a thinner in correction fluid products such as liquid paper. Many of its applications previously used carbon tetrachloride (which was banned in US consumer products in 1970). In turn, 1,1,1-trichloroethane itself is now being replaced by other solvents in the laboratory.


1,1,1-Trichloroethane, Safety
Although not as toxic as many similar compounds, inhaled or ingested 1,1,1-trichloroethane does act as a central nervous system depressant and can cause effects similar to those of ethanol intoxication, including dizziness, confusion, and, in sufficiently high concentrations, unconsciousness and death. Fatal poisonings and illnesses linked to intentional inhalation of trichloroethane have been reported. The removal of the chemical from correction fluid commenced due to Proposition 65 declaring it hazardous and toxic.


1,1,1-Trichloroethane, Safety
Prolonged skin contact with the liquid can result in the removal of fats from the skin, resulting in chronic skin irritation. Studies on laboratory animals have shown that 1,1,1-trichloroethane is not retained in the body for long periods of time. However, chronic exposure has been linked to abnormalities in the liver, kidneys, and heart. Pregnant women should avoid exposure, as the compound has been linked to birth defects in laboratory animals (see teratogenesis).


1,1,1-Trichloroethane, Atmospheric concentration
The Montreal Protocol targeted 1,1,1-trichloroethane as one of those compounds responsible for ozone depletion and banned its use beginning in 1996. Since then, its manufacture and use have been phased out throughout most of the world. Its atmospheric presence has declined rapidly due to its relatively short lifetime of about 5 years.


1,1,1-Trifluoroacetylacetone
1,1,1 -Trifluoroacetylacetone is the organofluorine compound with the formula CF3C(O)CH2C(O)CH3. It is a colorless liquid. Like other 1,3-diketones, it is used as a precursor to heterocycles, e.g. pyrazoles, and metal chelates. It is prepared by condensation of esters of trifluoroacetic acid with acetone.


1,1,1-Trifluoroacetylacetone
According to an analysis by proton NMR spectroscopy, the compound exists predominantly (97% at 33 °C, neat) as the enol. For comparison under the same conditions, the percent enol for acetylacetone and hexafluoroacetylacetone are 85 and 100%, respectively.


1,1,1-Trifluoroethane
1,1,1 -Trifluoroethane, or R-143a or simply trifluoroethane, is a hydrofluorocarbon (HFC) compound that is a colorless gas. It should not be confused with the much more commonly used HFC gas R-134a, nor confused with the isomeric compound 1,1,2-trifluoroethane. 1,1,1 -Trifluoroethane has a critical temperature of 73 °C.


1,1,1-Trifluoroethane, Applications
Trifluoroethane  is used as a refrigerant either by itself or more commonly as a component of blended mixtures. It is also used as a propellant in canned air products used to clean electronic equipment.


1,1,1-Trifluoroethane, Environmental effects
Unlike CFCs used as refrigerants, trifluoroethane has no chlorine atoms and therefore is not ozone-depleting. Its high chemical stability and infra-red absorbency make it a potent greenhouse gas with a lifetime of about 50 years and a global warming potential of 4300, which are at the high end compared to many other commonly used HFC refrigerants. Its abundance in the atmosphere more than doubled from about 10 parts per trillion (ppt) in 2010 to near 25 ppt in 2020.


1,1,1-Tris(aminomethyl)ethane
1,1,1 -Tris(aminomethyl)ethane (TAME) is an organic compound with the formula CH3C(CH2NH2)3. It is a colorless liquid. It is classified as a polyamine tripodal ligand, i.e., capable of binding to metal ions through three sites and hence is a tridentate chelating ligand, occupying a face of the coordination polyhedron.


1,1,1-Tris(aminomethyl)ethane, Preparation
TAME is synthesized by the Pd/C-catalyzed hydrogenation of 1,1,1-tris(azidomethyl)ethane. Although azides are potentially explosive, they are excellent and practical source of primary amines. The required tris(azidomethyl)ethane is obtained from the tritosylate by salt metathesis using sodium azide. These two steps are:


1,1,1-Tris(aminomethyl)ethane, Complexes of TAME
The tripodal TAME ligand coordinates facially to metal ions. This stereochemical feature has been exploited in the preparation of platinum(IV) cage complexes, e.g., [Pt(tame)2]4+, which is a six coordinate Pt(IV) complex. Platinum in its +4 oxidation state has a d6 configuration and is kinetically inert. For this reason the formation of [Pt(tame)2]4+ is initiated by installing TAME on a platinum(II) precursor. The resulting square planar complex is oxidized with [PtCl6]2− to produce the target Pt(IV) derivatives.
