Add dipole-dipole interactions
An '''intermolecular force''' is a force acting between molecules. The weakest of these is the [[Van der Waals force]], which is formed through electrostatic attaction.

==Dipole-dipole interactions==
Dipole-dipole interactions are occur between permanent [[dipole]]s in [[molecule]]s. The strength depends on the distance and relative orientation of the dipoles. The dipole-dipole interactions are weaker than the [[Hydrogen bond]] but stronger than the Van der Waals force.
Interactions between dipoles and [[Ion]]s are also possible.
