MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

Colligative properties are those properties of a solution that depend only on the number of solute particles and not on their nature. The four colligative properties are: 1. Relative lowering of vapour pressure 2. Elevation of boiling point 3. Depression of freezing point 4. Osmotic pressure Vapour pressure, boiling point, and freezing point are not colligative properties themselves; rather, their changes (lowering, elevation, and depression, respectively) are colligative properties. Therefore, osmotic pressure is the only colligative property among the given options. Answer: osmotic pressure
