Reaction of iso-propylbenzene with O ₂ followed by the treatment with H ₃ O ⁺ 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)

Options

  1. AReaction of R with O ₂ in the presence of light gives phosgene gas
  2. BQ reacts with aqueous NaOH to produce Cl ₃ CCH ₂ OH and Cl ₃ CCOONa
  3. CS on heating gives P
