Answer to Question #305459 in General Chemistry for gra

Question

How does the polarity of a substance affect the forces of attraction between the molecules?

Answer 1

Polarity also affects the strength of intermolecular forces. The only intermolecular force that non-polar molecules exhibit is the van der Waals force. Polar molecules can bond with each other via dipole-dipole interactions, which are generally stronger than van der Waals forces.
