The reaction\[{{C}_{6}}{{H}_{6}}+C{{H}_{3}}CI\xrightarrow[(anhydrous)]{AlC{{l}_{3}}}HCl+{{C}_{6}}{{H}_{5}}C{{H}_{3}}\]is:

A)  Friedel-Craffs alkylation

B)  addition reaction

C)   Friedel-Craffs acylation

D)  Friedel-Craffs benzylation

Correct Answer: A

Solution :

                 Friedel-Crafts reactipn: When benzene reacts with alkyi halide in presence of anhydrous \[\text{AlC}{{\text{l}}_{\text{3}}}\text{,}\]then alkyl benzene is obtained. This reaction is known as Friedal-Crafts alkylation.
