Reaction of iso-propylbenzene with \(O_2\) followed by the treatment with \(H_3O^+\) forms phenol and a by-product P. Reaction of P with 3 equivalents of \(Cl_2\) gives compound Q. Treatment of Q with \(Ca(OH)_2\) produces compound R and calcium salt S.
The correct statement(s) regarding P, Q, R and S is(are)
(A) Reaction of P with R in the presence of KOH followed by acidification gives
(B) Reaction of R with \(O_2\) in the presence of light gives phosgene gas
(C) Q reacts with aqueous NaOH to produce \(Cl_3CCH_2OH\) and \(Cl_3CCOONa \)
(D) S on heating gives P
