Solution
The correct options are A B C D All reactions produce phenol. (a) Benzene can react with N2O in the vapor phase at an elevated temperature to give phenol and nitrogen.
(b) The nitration of benzene followed by reduction produces aniline (A). Aniline on diazotization and hydrolysis produces phenol.
(c) Sodium benzenesulphonate when treated with fused NaOH produces sodium phenoxide which on reaction with H+ produces phenol.
(d) Friedel-Crafts alkylation of benzene with n-propylchloride gives cumene (isopropyl benzene). Cumene converts into phenol and acetone.
