Question:

Ammonolysis of Alkyl halides followed by the treatment with NaOH solution can be used to prepare primary, secondary and tertiary amines. The purpose of NaOH in the reaction is :

1. to remove basic impurities

2. to activate $\mathrm{NH}_{3}$ used in the reaction

3. to remove acidic impurities

4. to increase the reactivity of alkyl halide

Correct Option: , 3

Solution:

So the purpose of $\mathrm{NaOH}$ in the above reactions in to remove acidic impurities.
