Intermolecular forces and vapor pressure

Why does benzene have a higher vapor pressure than CHCl
3
? Since the intermolecular forces are stronger in benzene shouldn't it have a lower vapor pressure!

Why would you think the intermolecular forces are stronger in benzine?
Did you draw lewis dot structures for both components and thought about their properties?
You are right that as intermolecular forces increase, vapor pressure decreases.

I saw the boiling points of these two molecules and saw that benzene had a higher one, thus I thought that benzene had a stronger intermolecular force since the higher the boiling point=stronger intermolecular forces

- boiling points of these two molecules -
First, a molecule has no boiling point. BP is a macroscopic property.
-----------
One of factors affecting BP are substances dissolved in a liquid, in particular gases of ambient atmosphere.
