Chapter 10, Problem 87P

(a)

Interpretation Introduction

Interpretation:

The primary amine starting material should be identified to form a 4-Methyl-2-pentene via Hofmann degradation.

Concept introduction:

Generally amines can’t undergo elimination reaction, therefore amines can be converted in to quaternary ammonium halide by treating with ethyl iodide in basic solution of potassium carbonate.

In the reaction, quaternary ammonium halide can be converted in to quaternary ammonium hydroxide by using aqueous silver oxide.

Hofmann elimination:

Quaternary ammonium ion undergoes elimination when using strong base like hydroxide ion this reaction is called as Hofmann elimination.

In the reaction, proton abstraction is takes place in β- carbon atom, which is having more number of hydrogen.
