*Vapor pressure is directly related to the intermolecular force (IMF) keeping the liquid molecules held together. Therefore, the higher the IMF, the less amount of vapor particles are in the gas phase, and therefore, the lower the vapor pressure. |

Boiling point is the temperature where the vapor pressure = atmospheric pressure in the container.
Boiling point is a function of IMF and MW (molecular weight or molar mass).
