Question

The given compound (Benzophenone) can be obtained by Friedel Crafts reaction of benzene with which of the following compounds?

• A. Benzyl chloride
• B. Chlorobenzene
• C. Benzoyl chloride
• D. None of these

Answer 1

The correct option is C Benzoyl chloride

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 $(RC\equiv O^{+}$) made available by the reaction of acid halide and an anhydrous lewis acid.
Here, benzene reacts with $C_6{H}_{5}COCl$ in the presence $AlC{l}_3$ to give $C_6{H}_{5}CO{C}_6{H}_5$ (Benzophenone).
This reaction occurs by
(i) Formation of ayclium ion

(ii) Formation of Wheland intermediate

(iii) Removal of proton from the intermediate.
