Answer:

The higher the vapor pressure will be if the IM forces are weak.

Explanation:

higher the vapour pressure will be if the IM forces are weak.

the vapour pressure is the pressure exerted by vapour molecules on a solid/liquid surface with which it is in a state of equilibrium, which means as long as there is an equilibrium, vapour molecules enter the liquid phase and liquid molecules enter the vapour phase.If the IM forces between the liquid molecules are strong it will not easily leave the liquid phase and hence reduce the vapour pressure and consequently its boiling point will be higher.If the IM forces between the liquid molecules are weak they will easily leave the liquid phase and enter the vapour phase and hence have low boiling points

look at the relation b/w the following:
boiling point
vapour pressure
temperature
intermolecular forces..
