Solution

The correct option is D Osmotic pressure
Colligative properties are properties of solution which depend on the number of particles present in solution.

Elevation in boiling point, pressure, depression in vapour pressure, and depression in freezing point are colligative properties.

Osmotic pressure is proportional to the concentration of solute particles ci and is, therefore, a colligative property.
π∝n.

Hence, option D is correct.

Q. Which term is NOT an example of a colligative property?
Q. Which of the following is an example of a colligative property?
Q. The experimental values of colligative properties of many solutes in solution resembles calculated values of colligative properties.
However in some cases, the experimental values of colligative properties differ widely than those obtained by calculations. Such experimental values of colligative properties are known as abnormal values of colligative properties. The causes for abnormal values of colligative properties are:
(i) Dissociation of solute: It increases the colligative properties.
e.g.: Dissociation of KCl, NaCl etc. in H2O.
(ii) Association of solute: It decreases the colligative properties.
e.g.: Dimerisation of acetic acid in benzene.

If the degree of dissociation of an electrolyte A2B3 is 25% in a solvent, then:
Q. Assertion :Osmotic pressure of 1M glucose is lesser than 1M NaCl(aq) but vapour pressure of 1M glucose is higher than 1M NaCl. Reason: Osmotic pressure is colligative property but vapour pressure is not colligative property however, lowering in V.P. is colligative property.
