Chapter 23, Problem 23.70P

Interpretation Introduction

Interpretation:

The complete mechanism for the given reaction is to be drawn. Whether the significant amount of meta product is expected is to be explained.

Concept introduction:

The arenediazonium ion is electrophilic in nature due to the (${\text{N}}_{\text{2}}^{\text{+}}$) group and can undergo electrophilic aromatic substitution reaction with another aromatic ring. Such type of reaction is called azo coupling reaction, as the $\text{-N=N-}$ group, joins the two aromatic rings together. This $\text{-N=N-}$ group is called the azo group.
