Which of the following statements accurately describes the structure of urea?
A
A carbonyl group bonded to two –NH2 groups.
B
A C atom double bonded to two N atoms.
C
A carbonyl group bonded to a –CH3 group and a –NH2 group.
D
A carbonyl group bonded to two –OH groups.
Verified step by step guidance1
Identify the functional groups mentioned in the options: a carbonyl group is a C=O bond, and an –NH2 group is an amine group.
Understand the structure of urea: Urea is an organic compound with the formula CO(NH2)2.
Break down the formula CO(NH2)2: This indicates a carbonyl group (C=O) bonded to two amine groups (–NH2).
Compare the structure of urea with the options provided: Look for the option that describes a carbonyl group bonded to two –NH2 groups.
Conclude that the correct description of urea's structure is a carbonyl group bonded to two –NH2 groups, matching the first option.
