A ketone is an organic molecule, that has a carbonyl functional group (as do aldehydes) which consists of a carbon atom double bonded to an oxygen atom. For the molecule to be a ketone there must be two carbon atoms bonded to the carbon that is part of the carbonyl group. It has the structure of R1C=OR2.
When naming ketones, take the parental alkane prefix (based on the number of carbons in the carbon chain) and add the suffix '-one' to the end.
Reactions of Ketones
It is often made by Oxidation reaction of Secondary alcohol, whereas aldehyde is made by Oxidation reaction of Primary alcohol. A ketone can also be reduced back into the Secondary alcohol. In a ketone the Carbonyl group, which is usually a functional group, is between two of the same or different R groups.
