White phosphorus reacts with sulphuryl chloride to form ( PCl ₅ ) and (X ). Chlorine reacts with (X ) in the presence of wood charcoal to form (Y . X ) and (Y ) are respectively

Options

  1. A( SO ₂, SO ₂ Cl ₂ )
  2. B( SO ₂, SCl ₄ )
  3. C( SO ₃, SO ₂ Cl ₂ )
  4. D( SO ₃, SCl ₄ )

Correct answer

A. ( SO ₂, SO ₂ Cl ₂ )

Step-by-step solution

White phosphorus reacts with sulphuryl chloride to form ( PCl ₅ ) and ( SO ₂(X) ). Chlorine reacts with ( SO ₂ ) in presence of wood charcoal to form ( SO ₂ Cl ₂(Y) ). The reaction can be written as: ( P ₄ (white) +10 SO ₂ Cl ₂ 4 PCl ₅+ (X) 10 SO ₂ ) ( (X) SO ₂ + Cl ₂ Wood charcoal SO ₂ (Y) Cl ₂ )
