Interpretation Introduction

Interpretation:

The structure of the product of given reaction is to be drawn and the formation of benzyne intermediate is to be explained.

Concept introduction:

A nucleophilic aromatic substitution reaction is a substitution reaction in which the nucleophile displaces a good leaving group such as halide on the aromatic ring. Generally, proton transfer is the first step for the formation of nucleophile. Diels-Alder is one of the important reactions in organic synthesis. The Diels –Alder reaction involves diene and dienophile. Adiene contribute four Pi-electrons from a pair of conjugated pi-bond. And dienophile contributes two electrons from single pi-bond.
