Pick out the wrong statement(s). (i) Vapour pressure of a liquid is the measure of the strength of intermolecular attractive forces. (ii) Surface tension of a liquid acts perpendicular to the surface of the liquid. (iii) Vapour pressure of all liquid is same at their freezing points. (iv) Liquids with stronger intermolecular attractive forces are more viscous than those with weaker intermolecular force.

A(ii), (iii) and (iv)
B(ii) and (iii)
C(i), (ii) and (iii)
D(iii) only
Correct Answer

Solution

The freezing point is defined as the temperature at which the vapor pressure of the substance in its' liquid phase is equal to its' vapor pressure in the solid phase.
$$\Longrightarrow $$ Vapor pressure of liquids varies at their freezing points from one liquid to another liquid.
