Ion-dipole interaction (dipole-ion interaction): A noncovalent attraction between one pole of a bond dipole and an oppositely-charged ion. The Î´+ end of the bond dipole is attracted to an anion, and the Î´- end of the bond dipole is attracted to a cation.
Induced Dipole Forces. Forces between essentially non-polar molecules are the weakest of all intermolecular forces. Temporary dipoles are formed by the shifting of electron clouds within molecules. These temporary dipoles attract or repel the electron clouds of nearby non-polar molecules.
