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

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

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.
