Which intermolecular force increases with increasing molar mass?

Question

Quizplus · Accepted Answer

Dispersion forces increase with increasing molar mass because larger molecules have more electrons, which can form temporary dipoles and induce dipoles in neighboring molecules. This increases the strength of the dispersion forces. Dipole-dipole forces and hydrogen bonding are dependent on molecular polarity and functional groups, rather than molar mass, and X-forces is not a recognized intermolecular force.
