IMF & heat capacity and boiling point

Is heat capacity proportional to IMFs? If yes, then it would be proportional to boiling point too, right?
So if substance A has greater heat capacity than substance B, would substance A have greater IMFs too?
Thank you!

You bet.

Strength of IMF

The heat of fusion (heat required to melt a solid) and heat of vaporization (heat required to vaporize a liquid) are determined by the strength of the Intermolecular Forces. Substances with high IMF will have higher melting and boiling points. It will require more energy to break the IMF.
