Sulphide ore on roasting gives a gas X . X reacts with Cl ₂ in the presence of activated charcoal to give Y . Y is

Options

  1. ASO ₂ Cl ₂
  2. BS ₂ Cl ₂
  3. CSCl ₆
  4. DSOCl ₂

Correct answer

A. SO ₂ Cl ₂

Step-by-step solution

When sulphite ore is roasted it means that sulphide ore is being heated in the presence of excess of air to form a gas SO ₂ . From sulphide ore) S + O ₂ (X) SO ₂ e.g. 2 ZnS +3 O ₂ 2 ZnO +2 SO ₂ Thereafter, X reacts with Cl ₂ in the presence of activated charcoal to give Y
