- Dispersion Forces Dispersion forces are the weakest of all intermolecular forces. They are often called London forces after Fritz London (1900 - 1954), who first proposed their existence in 1930.

Van der Waal's forces are the weakest in chemistry. Van der Waal's forces are the attractions and repulsions between atoms and molecules. Van der Waal's forces are weak forces as they depend on the distance between the atoms and these forces arise due to interactions between uncharged atoms and molecules.
The forces are relatively weak, however, and become significant only when the molecules are very close. Larger and heavier atoms and molecules exhibit stronger dispersion forces than do smaller and lighter atoms and molecules.
