검증된 단계별 안내1
Identify the atoms present in each functional group listed: Carbonyl, Carboxyl, Hydroxyl, and Amino groups.
Recall that a Carbonyl group consists of a carbon atom double bonded to an oxygen atom, so it contains only carbon and oxygen atoms.
Understand that a Carboxyl group contains a carbonyl group plus a hydroxyl group, so it includes carbon, oxygen, and hydrogen atoms.
Recognize that a Hydroxyl group consists of an oxygen atom bonded to a hydrogen atom, so it contains oxygen and hydrogen atoms.
Know that an Amino group contains nitrogen and hydrogen atoms bonded to carbon, so it includes nitrogen, hydrogen, and carbon atoms.
