Only molecules which do not have dipole moments can experience dispersion forces.

Question

Quizplus · Accepted Answer

Dispersion forces, also known as London forces, can act on all molecules, but they are generally weaker than other intermolecular forces. These forces arise from the tendency of the electron distribution in a molecule or atom to temporarily become asymmetric, resulting in a temporary dipole moment. Therefore, even molecules with dipole moments can experience dispersion forces.
