MCQ
Tertiary amines have lowest boiling points amongst isomeric amines because:
- AThey have highest molecular mass.
- ✓They do not form hydrogen bonds.
- CThey are more polar in nature.
- DThey are most basic in nature.
✓
Answer
Correct option: B.
They do not form hydrogen bonds.
Primary and secondary amines can form hydrogen bonds whereas tertiary amines fail to do so. Hence, their boiling points are lowest.
