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.
Types of Intermolecular Interactions. Ion-dipole interactions occur when ions interact with polar molecules and represent the strongest of the forces that are discussed here. The charged ions are attracted to the dipole with the opposite partial charge. You have witnessed the results of this type of interaction if have ever seen table salt dissolved into a glass of water.
