No, it's an acid. The carbonyl group (carbon double-bonded to oxygen, CO) has a hydroxy group (oxygen single-bonded to hydrogen, OH) on one side, which makes it an acid. The combined group (COOH) is called a carboxyl group.
A ketone has the carbonyl group with aliphatic carbon groups (like methyl, ethyl, propyl, butyl) on either side of it.
Publius; Thank you! Appreciate the correction and the information!
