Which of the following gives propylamine upon hydrolysis?
  1. $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{C} \equiv \mathrm{N}$
  2. $\left(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2}ight)_{2} \mathrm{NH}$
  4. $\mathrm{CH}_{3} \mathrm{CH}_{2}-\mathrm{CH}=\mathrm{NH}$

Solution

Amides are hydrolysed to give acids and $\mathrm{NH}_{3}$ or amines. *
