In 1945, a woman named Beulah Hunter, who was 25 at the time, gave birth to a healthy, normal daughter named Penny Diana after the record-breaking pregnancy. According to the New Health Guide, the length of the pregnancy was verified by her menstrual cycle and the date of her positive pregnancy test.
In chemistry, a ketone (alkanone) /ËkiËtoÊn/ is an organic compound with the structure RC(=O)R', where R and R' can be a variety of carbon-containing substituents. Ketones and aldehydes are simple compounds that contain a carbonyl group (a carbon-oxygen double bond).
Best Answer: They are not the same--actually, they are very different. But one has to know a bit of organic chemistry to appreciate the difference. Acetone is a KETONE, and iso-propanol (rubbing alcohol) is an ALCOHOL. Or classified another way, ketones are polar aprotic [note the 'a' in aprotic] solvents; alcohols are polar protic solvents. It is the polar aprotic nature of actone that allows it to dissolve fingernail polish. Acetone is also used as paint thinner, among other things.
