Chapter 19.14, Problem 19.20P

(a)

Interpretation Introduction

Interpretation:

The major product, when the given amine undergoes exhaustive methylation, treatment with ${\text{Ag}}_2\text{O}$, and heating is to be predicted.

Concept introduction:

Hofmann elimination reactions comprise the conversion of an amine into an alkene. The quaternary ammonium salt is formed as an intermediate in these reactions followed by beta elimination to form the desired product. The major alkene will have less substitution at double bond of the alkene compound.

(b)

Interpretation Introduction

Interpretation:

The formation of major product, when the given amine undergo exhaustive methylation, treatment with ${\text{Ag}}_2\text{O}$, and heating is to be predicted.
