(a)

Interpretation Introduction

Interpretation:

Synthesis of 1-hexanamine has to be proposed from a bromoalkane of six carbon atoms.

Concept introduction:

Preparation of primary amines:

It can be prepared in greater yield by treating a haloalkane with strong nucleophile like potassium azide or sodium azide and followed by reduction in presence of $LiAl{H}_4$ to form the corresponding amine.

Reduction: If electrons are gained to a species or hydrogen atoms are added to a species or oxygen atom gets removed from a species during a chemical reaction is known as reduction. In certain reaction, $LiAl{H}_4$ (Lithium aluminium hydride) is used as a reducing agent.

Interpretation Introduction

Interpretation:

Synthesis of 1-hexanamine has to be proposed from a bromoalkane of five carbon atoms.

Concept introduction:

Formation of nitrile:

A haloalkane reacts with potassium cyanide $\left(KCN\right)$ to form the corresponding nitrile.

  $RC{H}_{2}Br\text{ + KCN }\underset{}{\to }RC{H}_{2}CN+\text{ KBr}$

Reduction: If electrons are gained to a species or hydrogen atoms are added to a species or oxygen atom gets removed from a species during a chemical reaction is known as reduction. In certain reaction, $LiAl{H}_4$ (Lithium aluminium hydride) is used as a reducing agent.
