Interpretation Introduction

Interpretation:

The explanation of more rapidly reaction of $\text{m-xylene}$ or $\text{p-xylene}$ with ${\text{Cl}}_{\text{2}}+{\text{FeCl}}_{\text{3}}$ is to be given.

Concept Introduction:

Aromatic compounds such as benzene which is having closed ring and alternate double bonds undergo electrophilic aromatic substitution reactions.  Electrophilic aromatic substitution takes place when an electrophile displaces a hydrogen atom of an aromatic ring.  There are five most common electrophilic aromatic substitution reactions that are halogenation, nitration, sulfonation, Friedel-Crafts acylation and Friedel-Crafts alkylation.  All these reactions take place by same two-step mechanism.
