Solution

The correct option is B Surface tension
Surface tension is not a colligative property of the solution. Surface tension is a surface phenomenon.
Colligative property is a bulk phenomenon.
Osmotic pressure, lowering of vapour pressure, elevation in boiling point and depression in freezing point are colligative properties of the solution.

Q. Assertion :Osmotic pressure of

1 M

glucose is lesser than

1 M

N a C l (a q)

but vapour pressure of

1 M

glucose is higher than

1 M

N a C l

. Reason: Osmotic pressure is colligative property but vapour pressure is not colligative property however, lowering in V.P. is 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

H_{2} O

.
(ii) Association of solute: It decreases the colligative properties.
e.g.: Dimerisation of acetic acid in benzene.

Q. (A) Vapour pressure is a colligative property.
(R) Colligative property depends on the number of solute particles dissolved in the solution.
