Web17 jul. 2024 · Ion dipole interactions are stronger than the dipole-dipole interactions because an ion has a much stronger charge than a dipole when compared. Ion-dipole interactions are even stronger than hydrogen bonds. The ions align with a polar molecule in such a way that the positive ions are close to the negative part of the dipole and vice … WebA common example of ion-dipole interaction in biological organic chemistry is that between a metal cation, most often Mg +2 or Zn +2, and the partially negative oxygen of a carbonyl. London dispersion forces. Nonpolar molecules such as hydrocarbons also are subject to weaker but still significant attractive intermolecular attractive forces.
