The boiling point will increase.
Work Step by Step
As intermolecular forces increase, fewer molecules will have the necessary energy needed to completely overcome the intermolecular forces and vaporize at that given temperature. Thus, more energy (in the form of an increase in temperature) will be needed for the molecules to completely overcome the intermolecular forces and become gaseous. Furthermore, higher intermolecular forces will result in a higher temperature necessary to boil the liquid, meaning the boiling point will increase.
