Particles in liquids have a range of kinetic energies. The most energetic particles have enough energy to escape from the liquid surface and enter the gas phase. It can be said that a substance is more volatile when it is easier for the particles to enter the gas phase. 

Now intermolecular forces of attraction (IMFA) are responsible for holding the particles together, so the weaker the IMFA the easier the particles could escape to the gas phase, thus the more volatile.
