Which of the following forces between particles is NOT considered a van der Waals force?
Force between two instantaneously induced dipoles (London dispersion force)
Force between two permanent dipoles
Force between a permanent dipole and an induced dipole
Force between an ion and a dipole
Attractive intermolecular forces are known as van der Waals forces,
These forces are other than due to covalent bonds, the hydrogen bonds, or the electrostatic interaction of ions with one another or with neutral molecules or charged molecules. The term includes:
Note that attractive forces between an ion and a dipole are known as ion-dipole forces and these are not van der Waals forces.
