WebLecture: Intermolecular Forces
Kotz and Triechel, Chemistry and Chemical Reactivity Chapter 11: Sections 1-3.
Intermolecular forces called van der Waals forces hold molecules together to form solids. As with all chemical "bonds", the forces have their basis in electrical charges, in the electrons in their shells and protons of the nucleus of the atoms. But the bonds between molecules are much weaker than the electron-sharing bonds within molecules that we studied in chapters 7-9.
Examples of ion-dipole situtions include whenever a metal ion bonds to polar water molecules to form hydrated salts.
