Question

Identify the major products P,Q,R in the following sequence of reactions :

Benzene + Propyl Chloride ----Anhydrous AlCl₃---> P

P-----(i)O₂/(ii)H₃O⁺------>Q + R.

Answer 1

Benzene reacts with Propyl Chloride in the presence of Anhydrous AlCl3 to give Isopropyl benzene.
so P is Isopropyl benzene.

Isopropyl benzene reacts with 1) Oxygen and ii) H₃O⁺ to produce Phenol and Acetone
so Q is Phenol and R is Acetone
