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.
Ion-Dipole Forces. An ion-dipole force is just what its name says. It is a force between an ion and a dipole molecule. Remember that an ion is an atom that has gained or lost one or more electrons and therefore has a negative or positive charge.earn the different intermolecular bonds (including hydrogen bonding, dipole-dipole and ion-dipole forces), their strengths, and their effects on properties, such as boiling and melting points, solubility, and evaporation.
