MCQ
Equimolar solutions in the same solvent have
  • A
    Same boiling point but different freezing point
  • B
    Same freezing point but different boiling point
  • ✓
    Same boiling and same freezing points
  • D
    Different boiling and different freezing points
✓

Answer

Correct option: C.
Same boiling and same freezing points
c
The elevation in the boiling point and the depression in the freezing point are colligative properties and depend on the number of solute particles. Equimolar solutions of non-electrolytes have the same number of solute particles.

Hence, equimolar solutions of two non-electrolytes in the same solvent have the same boiling point and same freezing point.
