Chapter 18.10, Problem 18.10P

(a)

Interpretation Introduction

Interpretation:

The conversion of hexanoic acid to given amine has to be shown.

Concept introduction:

Acid chlorides are most often prepared by treating a carboxylic acid with thionyl chloride.

Reaction of acid chloride with ammonia or amines:

The reaction of acid chlorides with ammonia and primary and secondary amines will yield amide.

The nucleophilic addition of ammonia or amine to the carbonyl carbon occurs which is followed by a proton transfer forming an addition intermediate that will eliminate chloride and lose a proton to give the amide compound.

$LiAl{H}_4$ is a powerful reducing agent which reduces carboxylic acids to primary alcohol.
