Multiple Choice
Which of the following functional groups is characterized by a carbon double-bonded to an oxygen and single-bonded to a hydroxyl group?
A
Carboxyl group
B
Carbonyl group
C
Amino group
D
Hydroxyl group
Verified step by step guidance
1
Identify the functional groups listed in the problem: Carboxyl group, Carbonyl group, Amino group, and Hydroxyl group.
Understand the structural characteristics of each functional group. A Carboxyl group is characterized by a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group (OH).
Recognize that a Carbonyl group consists of a carbon atom double-bonded to an oxygen atom, but it does not include a hydroxyl group.
Note that an Amino group contains a nitrogen atom bonded to hydrogen atoms, and a Hydroxyl group consists of an oxygen atom bonded to a hydrogen atom.
Conclude that the functional group characterized by a carbon double-bonded to an oxygen and single-bonded to a hydroxyl group is the Carboxyl group.
