MCQ

The correct statement among the following is:

A
Boiling point of amine is more than that of alcohol of nearly same molecular mass.
B
The solubility of amines in water increases with increase in molecular mass.
✓
The order of boiling point of isomeric amines is primary $>$ secondary $>$ tertiary.
D
None of these

✓

Answer

Correct option: C.

The order of boiling point of isomeric amines is primary $>$ secondary $>$ tertiary.

Boiling point of amines have high boiling point due to presence of hydrogen bonding between amine molecules.
But the boiling point decreases with increase in alkyl groups attached to the $N$ atom, because the number of $H$ atoms present for hydrogen bonding decreases.
