검증된 단계별 안내1
Identify the functional groups listed in the problem: amino group, hydroxyl group, carbonyl group, and carboxyl group.
Understand the structure of an alcohol. Alcohols are organic compounds characterized by the presence of a hydroxyl group (-OH) attached to a carbon atom.
Recognize that the hydroxyl group is the defining feature of alcohols. It is responsible for the properties and reactions typical of alcohols.
Compare the hydroxyl group with the other functional groups listed: amino group (-NH2), carbonyl group (C=O), and carboxyl group (-COOH). Note that none of these are characteristic of alcohols.
Conclude that the functional group present in alcohols is the hydroxyl group, as it is the key structural component that defines alcohols.
