검증된 단계별 안내1
Identify the functional groups listed in the problem: amino group (-NH2), carboxyl group (-COOH), hydroxyl group (-OH), and carbonyl group (C=O).
Understand the structure of alcohols: Alcohols are organic compounds that contain one or more hydroxyl groups (-OH) attached to a saturated carbon atom.
Understand the structure of phenols: Phenols are aromatic compounds where a hydroxyl group (-OH) is directly bonded to a benzene ring.
Compare the functional groups present in alcohols and phenols: Both alcohols and phenols contain the hydroxyl group (-OH) as a key functional group.
Conclude that the hydroxyl group (-OH) is the functional group common to both alcohols and phenols, as it is present in both types of compounds.
