검증된 단계별 안내1
Identify the functional groups listed in the problem: Hydroxyl group, Carboxyl group, and Amino group.
Understand that a functional group is a specific group of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.
Recognize that the Hydroxyl group (\(\text{-OH}\)), Carboxyl group (\(\text{-COOH}\)), and Amino group (\(\text{-NH}_2\)) are all common functional groups in organic chemistry.
Note that the Sodium ion (\(\text{Na}^+\)) is not a functional group but rather a cation, typically found in inorganic chemistry or as a counterion in salts.
Conclude that the Sodium ion is not a functional group commonly found in organic molecules, unlike the other options listed.
