Consider the following sequence of reactions. The correct reagents ( P , Q, R and S ) required are:

Options

  1. AP = Br ₂ / red phosphorous; Q = H ₂ O ; R = SOCl ₂ ; S = H ₂, Pd ₂- BaSO ₄
  2. BP = Br ₂ / red phosphorous; Q = H ₃ O ⁺ ; R = SOCl ₂ ; S = LiAlH ₄
  3. CP = Br ₂ / NaOH ; Q = H ₂ O ; R = PCl ₃ ; S = DIBAL - H
  4. DP = PBr ₃ ; Q = H ₃ O ⁺ ; R = Cl ₂ / FeCl ₃ ; S = Pd - BaSO ₄

Correct answer

A. P = Br ₂ / red phosphorous; Q = H ₂ O ; R = SOCl ₂ ; S = H ₂, Pd ₂- BaSO ₄
