검증된 단계별 안내1
Identify the functional groups listed in the problem: Hydroxyl group (-OH), Amino group (-NH2), Carboxyl group (-COOH), and Carbonyl group (C=O).
Understand the structure of a carboxylic acid, which is characterized by the presence of a carboxyl group.
The carboxyl group is a combination of a carbonyl group (C=O) and a hydroxyl group (-OH) attached to the same carbon atom.
Recognize that the carboxyl group (-COOH) is the defining functional group of carboxylic acids, giving them their acidic properties.
Conclude that among the options provided, the carboxyl group (-COOH) is the characteristic functional group of carboxylic acids.
