London dispersion forces, under the category of van der Waal forces: These are the weakest of the intermolecular forces and exist between all types of molecules, whether ionic or covalentâpolar or nonpolar. The more electrons a molecule has, the stronger the London dispersion forces are.
Intermolecular forces are physical forces between molecules. They explain how molecules interact with each other. The strength or weakness of intermolecular forces determine the state of matter of a substance (e.g., solid, liquid, gas) and some of the chemical properties (e.g., melting point, structure).
