Question
Consider a 1°, 2° and 3° amine, all of equivalent molecular weight. Which amine is most likely to have the lowest boiling point?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Tertiary amines have the lowest boiling points among amines of similar molecular weight because they cannot form hydrogen bonds with each other (no N-H bond). Primary and secondary amines can form hydrogen bonds.
