Identify the ketone functional group, which is characterized by a carbonyl group (C=O) bonded to two carbon atoms. The general structure is R-CO-R', where R and R' are carbon-containing groups.
Examine each compound's structure to determine the presence of the ketone group:
1. Acetic acid (CH\_3COOH) contains a carboxylic acid group (-COOH), not a ketone.
2. Acetaldehyde (CH\_3CHO) contains an aldehyde group, where the carbonyl carbon is bonded to at least one hydrogen atom, not two carbons.
3. Acetone (CH\_3COCH\_3) has a carbonyl group bonded to two methyl groups, fitting the ketone definition.
4. Ethanol (CH\_3CH\_2OH) contains an alcohol (-OH) group, not a ketone.
