Tertiary amines have lowest boiling points amongst isomeric amine… - Vidyadip

MCQ

Tertiary amines have lowest boiling points amongst isomeric amines because:

A
They have highest molecular mass.
B
They do not form hydrogen bonds.
C
They are more polar in nature.
D
They are most basic in nature.

✓

Answer

They do not form hydrogen bonds.

Explanation:

Primary and secondary amines can form hydrogen bonds whereas tertiary amines fail to do so. Hence, their boiling points are lowest.
