Intermolecular Forces

What is the relationship between the intermolecular forces in a liquid and its vapor pressure?

• The vapor pressure of a liquid stays the same as the strength of its intermolecular forces increase.

• The vapor pressure of a liquid decreases as the strength of its intermolecular forces decreases.

• The vapor pressure of a liquid increases as the strength of its intermolecular forces increases.

• The vapor pressure of a liquid decreases as the strength of its intermolecular forces increases.

Which set molecules correctly orders them to show increasing boiling point?
