Aldehyde
An
aldehyde or
alkanal is an
organic compound containing a formyl group. The
formyl group is a
functional group, with the structure R-CHO, consisting of a
carbonyl center (a carbon double bonded to oxygen) bonded to
hydrogen and an
R group, which is any generic
alkyl or side chain. The group without R is called the
aldehyde group or
formyl group. Aldehydes differ from
ketones in that the carbonyl is placed at the end of a
carbon skeleton rather than between two carbon atoms. Aldehydes are common in
organic chemistry. Many
fragrances are aldehydes.
