Question

The reagent used for converting benzene to ethyl benzene is:

• A. $ {{\text{C}}_{2}}{{H}_{5}}Cl, $ anhydrous $ AlC{{l}_{3}} $
• B. $ {{C}_{2}}{{H}_{5}}Cl, $ aqueous $ AlC{{l}_{3}} $
• C. $ {{C}_{2}}{{H}_{5}}OH, $ anhydrous $ AlC{{l}_{3}} $
• D. $ {{C}_{2}}{{H}_{5}}Cl,SOC{{l}_{2}} $

Answer 1

Answer: (A)

Friedel-Crafts reaction: This reaction is used to introduce alkyi (methyl or ethyl) group in benzene ring. In this reaction when benzene reacts with alkyi halide $ ({{C}_{2}}{{H}_{5}}Cl) $ in presence of anhydrous $ \text{AlC}{{\text{l}}_{\text{3}}} $ ethyl benzene is obtained.
