Question

Identify the major products P, Q and R in the following sequence of reactions: Benzene + CH3CH2CH2ClCH_3CH_2CH_2Cl AnhydrousAlCl3\xrightarrow{Anhydrous AlCl_3} P (i)O2,(ii)H3O+/Δ\xrightarrow{(i) O_2, (ii) H_3O^+/\Delta} Q + R

A

P: Cumene, Q: Phenol, R: Acetone

B

P: Propylbenzene, Q: Phenol, R: Propanoic acid

C

P: Propylbenzene, Q: Phenol, R: Propanol

D

P: Cumene, Q: Phenol, R: Acetone

Step-by-Step Solution

Friedel-Crafts alkylation of benzene with n-propyl chloride leads to rearrangement to isopropylbenzene (cumene). Oxidation of cumene with O2O_2 followed by acid hydrolysis yields phenol and acetone.
