Question

Which of the following amines has the highest boiling point for a similar molecular weight?
Options
A CH3CH2CH2NH2 (1° amine)
Correct Answer
B (CH3)2CHNH2 (1° branched)
C (CH3CH2)2NH (2° amine)
D (CH3)3N (3° amine)
Correct Answer

Option A is the correct answer.

Detailed Explanation

Primary and secondary amines can form intermolecular hydrogen bonds (N-H···N), increasing boiling points. Tertiary amines lack N-H bonds and have lower boiling points.

Hint

N-H bonds allow hydrogen bonding.
