Q45.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 NH3 used in the reaction (3) to remove acidic impurities (4) to increase the reactivity of alkyl halide.
What This Question Tests
This question probes the understanding of the role of NaOH in the ammonolysis of alkyl halides, which is to neutralize the acidic ammonium salt formed.

6.21 — Primary Alkyl Halide C4H9Br (A) Reacted With Alcoholic Koh To Give Compound (B).
Chemistry Class 12 · Chapter 6
6.21 Primary alkyl halide C4H9Br (a) reacted with alcoholic KOH to give compound (b). Compound (b) is reacted with HBr to give (c) which is an isomer of (a). When (a) is reacted with sodium metal it gives compound (d), C8H18 which is different from the compound formed when n-butyl bromide is reacted with sodium. Give the structural formula of (a) and write the equations for all the reactions.
