Carboxyl group
D
Hydroxyl group
Verified step by step guidance
1
Identify the functional groups listed in the problem: amino group, carbonyl group, carboxyl group, and hydroxyl group.
Understand the structure of each functional group: An amino group contains a nitrogen atom bonded to hydrogen atoms. A carbonyl group consists of a carbon atom double-bonded to an oxygen atom. A hydroxyl group is characterized by an oxygen atom bonded to a hydrogen atom.
Focus on the carboxyl group: It is characterized by a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group. This structure can be represented as .
Compare the structural characteristics of the carboxyl group with the description given in the problem: The carboxyl group matches the description of a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group.
Conclude that the functional group described in the problem is the carboxyl group, based on the structural match.
