Interpretation Introduction

Interpretation:

• Proposed a plausible mechanism of given following reactions have to be predicted.  

Concept Introduction:

• Electrophiles are electron deficient species. In Electrophilic substitution reaction a group or atom in a compound is replaced by electrophile. This kind of reaction occurs predominantly in aromatic compounds. Electrophilic substitution reactions of aromatic compounds are known as aromatic electrophilic substitution reactions.

• Benzene is an electron rich Aromatic compound. It undergoes aromatic electrophilic substitution reaction. 

• An elimination reaction is a kind of natural reaction in which two substituents are unconcerned from a molecule in also a one or two-step mechanism. The one-step mechanism is famous as the $\text{E2 }$reaction, and the two-step mechanism is known as the $\text{E1}$reaction.
