The colligative property is not represented by
1 Elevation in boiling point
2 Osmotic pressure
3 Optical activity
4 Relative lowering of vapour pressure
Explanation:
Colligative properties are defined as properties of dilute solutions of non-volatile solutes whose values depend upon the number of solute particles in the solution but not on the individual identity of the solute. Various colligative properties are : (1) Relative lowering of vapour pressure (2) Elevation in boiling point (3) Depression in freezing point (4) Osmotic pressure and optical activity is not a colligative property.
