Question:

Write structures of different isomers corresponding to the molecular formula, C3H9N. Write IUPAC names of the isomers which will liberate nitrogen gas on treatment with nitrous acid.

Solution:

      The structures of different isomers corresponding to the molecular formula, C3H9N are given below:

     (a) $\mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{NH}_{2}$

Propan-1-amine (10)

(b)

Propan-2-amine (10)

(c)

(d)

N,N-Dimethylmethanamine (30)

10amines, (a) propan-1-amine, and (b) Propan-2-amine will liberate nitrogen gas on treatment with nitrous acid.
