Acetone and carbon disulphide form binary liquid solution showing positive deviation from Raoult law. The normal boiling point (T) of pure acetone is less than that of pure CS₂. Pick out the incorrect statements among the following. (a) Boiling temperature of mixture is always less than boiling temperature of acetone. (b) Boiling temperature of Azeotropic mixture is always less than boiling temperature of pure CS₂. (c) When a small amount of CS₂ (less volatile component) is added to excess of acetone boiling point of resulting mixture increases. (d) A mixture of CS, and CH3COCH, can be completely separated by simple fractional distillation. Acetone and carbon disulphide form binary liquid solution showing positive deviation from Raoult law.
