Friedel Crafts Acylation:
In this reaction, one H-atom of the ring get replace by Acyl (RCO) group. The attacking electrophile is an acylium ion $(R C \equiv O^{+}$ ) made available by the reaction of acid halide and an anhydrous lewis acid.
This reaction occurs by
(i) Formation of ayclium ion
(ii) Formation of Wheland intermediate
(iii) Removal of proton from the intermediate.
Here, benzene reacts with $C H_{3} C O C l$ in the presence $A l C l_{3}$ to give $C_{6} H_{5} C O C H_{3} .$
