The Paperwork Reduction Act of 1980 (Pub. L. No. 96-511, 94 Stat. 2812, codified at 44 U.S.C. Â§Â§ 3501 â 3521) is a United States federal law enacted in 1980 designed to reduce the total amount of paperwork burden the federal government imposes on private businesses and citizens.
Alkanes, Alkenes & Alkynes. Alkanes, alkenes and alkynes are simple hydrocarbon chains with no functional groups. Alkanes are identified because the carbon chain has only single bonds. Common alkanes include methane (natural gas), propane (heating and cooking fuel), butane (lighter fluid) and octane (automobile fuel). Alkenes have at least one double bond and alkynes have at least one triple bond. The most common alkyne is ethyne, better known as acetylene. The generic formula for alkanes is C n H 2n+2, where n is the number identified by the prefix. Alkenes have the formula C n H 2n and alkynes use the formula C n H 2n-2.
An alkyne is a hydrocarbon containing a carbonâcarbon triple bond; the simplest member ofthis family is acetylene, HLC'CLH. The chemistry of the carbonâcarbon triple bond issimilar in many respects to that of the carbonâcarbon double bond; indeed, alkynes andalkenes undergo many of the same addition reactions.he sufï¬x ane in the name of the corresponding alkane is replaced by the sufï¬x yne, and the triple bond is given the lowest possible number.Substituent groups that contain a triple bond (called alkynyl groups) are named by replac-ing the ï¬nal e in the name of the corresponding alkyne with the sufï¬x yl.
