The order of boiling points of isomeric amines is:
ATertiary > primary > secondary
BPrimary > secondary > tertiary
CTertiary > secondary > primary
DSecondary > primary > tertiary
Answer & Solution
Correct answer: B. Primary > secondary > tertiary
1. A primary amine has two hydrogens for bonding.
2. A secondary amine has only one and a tertiary none.
3. More bonding means a higher boiling point.
