(a)
Interpretation:
The given molecules have to be ranked in the order of increasing boiling points.
Concept introduction:
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.
(b)
Interpretation:
The given molecules have to be ranked in the order of increasing boiling points.
Concept introduction:
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 functional group present in the molecule.
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.
