9. The stronger the intermolecular force, the lower the vapor pressure of a liquid at any given temperature. As a result, molecules that are primarily attracted by London dispersion forces will have higher vapor pressures than those attracted by dipole-dipole forces, which will in turn have higher vapor pressures than those with hydrogen bonding.

Here's why: Intermolecular forces are the attractive forces between molecules. For something to vaporize, you have to get enough energy together to break these forces. As a result, you'll need more energy (due to higher temperature) to break apart strong intermolecular forces.
