Which functional group is present in carboxylic acids?
Answer and explanation
Correct answer: Carboxyl group, \(-COOH\)
The characteristic functional group of carboxylic acids is the carboxyl group, \(-COOH\). It has a carbonyl part \(C=O\) and a hydroxyl part \(-OH\) attached to the same carbon atom. Thus, \(-OH\) alone is not the functional group of a carboxylic acid; it is characteristic of alcohols. For example, ethanoic acid \(CH_3COOH\) contains a \(-COOH\) group.
