Benzene reacts with\[C{{H}_{3}}COCl\]in the presence of\[AlC{{l}_{3}}\]and gives

A) \[{{C}_{6}}{{H}_{5}}COC{{H}_{5}}\]         

B) \[{{C}_{6}}{{H}_{5}}C{{H}_{3}}\]

C) \[{{C}_{6}}{{H}_{5}}OC{{H}_{3}}\]                            

D) \[{{C}_{7}}{{H}_{14}}\]

Correct Answer: A

Solution :

When benzene reacts with acetyl chlorine\[(C{{H}_{3}}COCl)\]in the presence of\[AlC{{l}_{3}}\], acylation of benzene takes place and acetophenone is obtained as product. This reaction is known as Friedel-Crafts acylation.
