Interpretation: The following pairs have to be ranked in order of increasing boiling point.
Concept Introduction: Vapor pressure is nothing but the pressure of a vapor in contact with its liquid or solid form.
When a liquid and vapor are in equilibrium the pressure exerted by the vapor is called the equilibrium vapor pressure.
Intermolecular force: The attractive force that withholds two molecules is called as intermolecular force. The influence of intermolecular forces depends on molar mass and the
If intermolecular force is small the vapor pressure of the substance is high and the boiling point will be low.
The boiling point of a liquid is the temperature at which its vapor pressure is equal to the external pressure.
