검증된 단계별 안내1
Identify the functional groups listed in the problem: Carbonyl group (C=O), Hydroxyl group (-OH), Carboxyl group (-COOH), and Amino group (-NH2).
Understand the structure of alcohols: Alcohols contain a hydroxyl group (-OH) attached to a saturated carbon atom.
Understand the structure of phenols: Phenols also contain a hydroxyl group (-OH), but it is directly attached to an aromatic ring.
Compare the functional groups present in both alcohols and phenols: Both contain the hydroxyl group (-OH).
Conclude that the functional group present in both alcohols and phenols is the hydroxyl group (-OH).
