Chapter 25, Problem 25.27P

Interpretation Introduction

(a)

Interpretation: The major product formed by the reaction of given amine with excess ${\text{CH}}_{\text{3}}\text{I}$ followed by ${\text{Ag}}_2\text{O}$ is to be drawn.

Concept introduction: Amines on reaction with excess ${\text{CH}}_{\text{3}}\text{I}$ followed by ${\text{Ag}}_{\text{2}}\text{O}$ undergo Hofmann elimination. The product formed by the Hofmann elimination of amines is alkene. The removal of proton from $\text{β}$ carbon atom of ammonium salt leads to the formation of $\text{π}$ bond of the alkene. The mechanism followed in the Hofmann elimination is $\text{E2}$.
