The colligative property is not represented by :

Options

A. Elevation in boiling point
B. Osmotic pressure
C. Optical activity
D. Relative lowering of vapour pressure

Answer

C

Explanation

Properties of dilute solutions of non - whose values depend upon the concentration and of solute particles in the solutions but out on the identity of the solute . These can be known as pressure . Various colligative properties are
(i) Relative lowering of vapour pressure
(ii) Elevation in boiling point
(iii) Depression in freezing point
(iv) Osmotic pressure
So , optical activity is not a colligative property .
