a)

Interpretation Introduction

Interpretation:

The synthesis of the given compound from benzene has to be shown

Concept Introduction:

Aromatic compounds such as benzene which has 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.
