MCQ
Which is not a colligative property
  • ✓
    Refractive index
  • B
    Lowering of vapour pressure
  • C
    Depression of freezing point
  • D
    Elevation of boiling point
✓

Answer

Correct option: A.
Refractive index
a
Colligative properties depend on how many solute particles are present as well as the solvent amount, but they do NOT depend on the type of solute particles.

Hence, Refractive Index is not a colligative particles as it only depends on nature of materials.
