QJEEAdv24Ch2fc5: JEE Advanced 2024 Chemistry - Class 12 JEEAdv24Ch2fc5 Solution: Reaction of iso-propylbenzene with 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)

Multiple Choice Options

  • A Reaction of R\mathbf{R} with O2\mathrm{O}_2 in the presence of light gives phosgene gas
  • B Q\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}
  • C S\mathbf{S} on heating gives P\mathbf{P}
  • D Reaction of P\mathbf{P} with R\mathbf{R} in the presence of KOH\mathrm{KOH} followed by acidification gives
