Answer:
The normal boiling point is the temperature in which the vapour pressure of a liquid becomes equal to atmospheric pressure. If the intermolecular forces are small, the liquid has a high vapour pressure. Little heat energy will have to be added to separate the molecules, so the boiling point will be low.
hope you get it..

Hey friend here’s your Answer:
The boiling point decreases as the vapour pressure increases.
Explanation:
Vapour Pressure
Some of the molecules at the surface of a liquid have enough kinetic energy to escape into the atmosphere.
These molecules exert a pressure on the walls of a closed container.
The vapour pressure is the pressure exerted when the molecules leave the surface at the same rate as they return. Boiling Point
The normal boiling point is the temperature in which the vapour pressure of a liquid becomes equal to atmospheric pressure.
If the intermolecular forces are small, the liquid has a high vapour pressure.
Little heat energy will have to be added to separate the molecules, so the boiling point will be low.
Conversely, if there are strong intermolecular forces, the molecules will be strongly attracted to each other.
Few molecules will enter the gas phase, and the vapour pressure will be low.
More heat will be required to separate the molecules, so the boiling point will be higher. HOPE THIS HELPS☺️
