Reaction of iso-propylbenzene with O_2 followed by the treatment...

Reaction of iso-propylbenzene with O2\mathrm{O}_2 followed by the treatment with H3O+\mathrm{H}_3 \mathrm{O}^{+}forms phenol and a by-product P\mathbf{P}. Reaction of P\mathbf{P} with 3 equivalents of Cl2\mathrm{Cl}_2 gives compound Q\mathbf{Q}. Treatment of Q\mathbf{Q} with Ca(OH)2\mathrm{Ca}(\mathrm{OH})_2 produces compound R\mathbf{R} and calcium salt S\mathbf{S}. The correct statement(s) regarding P,Q,R\mathbf{P}, \mathbf{Q}, \mathbf{R} and S\mathbf{S} is(are)Reaction of iso-propylbenzene with O_2 followed by the treatment with H_3 O^ + forms phenol and a by-product P .Reaction of iso-propylbenzene with O_2 followed by the treatment with H_3 O^ + forms phenol and a by-product P .Reaction of iso-propylbenzene with O_2 followed by the treatment with H_3 O^ + forms phenol and a by-product P .Reaction of iso-propylbenzene with O_2 followed by the treatment with H_3 O^ + forms phenol and a by-product P .

Options

  1. AReaction of P\mathbf{P} with R\mathbf{R} in the presence of KOH\mathrm{KOH} followed by acidification gives In the following reaction sequence, P , Q , S and T are the major products. The correct statement(s) about P , Q , S
  2. BReaction of R\mathbf{R} with O2\mathrm{O}_2 in the presence of light gives phosgene gas
  3. CQ\mathbf{Q} reacts with aqueous NaOH\mathrm{NaOH} to produce Cl3CCH2OH\mathrm{Cl}_3 \mathrm{CCH}_2 \mathrm{OH} and Cl3CCOONa\mathrm{Cl}_3 \mathrm{CCOONa}
  4. DS\mathbf{S} on heating gives P\mathbf{P}

Correct answer

A. Reaction of P\mathbf{P} with R\mathbf{R} in the presence of KOH\mathrm{KOH} followed by acidification gives In the following reaction sequence, P , Q , S and T are the major products. The correct statement(s) about P , Q , S
