Molecular dispersion is a type of intermolecular force that occurs between non-polar molecules. It is the weakest type of intermolecular force and is also known as London dispersion forces or induced dipole-induced dipole forces. The term "molecular dispersion" refers to the fact that these forces are present in all molecules, regardless of their polarity.

The origin of molecular dispersion forces lies in the temporary fluctuations of electron distribution within a molecule. These fluctuations create instantaneous dipoles, which can induce dipoles in neighboring molecules. The interaction between these induced dipoles results in a weak attractive force.

The strength of molecular dispersion forces increases with the size of the molecule. This is because larger molecules have more electrons, which leads to more significant fluctuations in electron distribution. As a result, the induced dipoles are stronger, and the attractive force between molecules is greater.

Molecular dispersion forces are responsible for the physical properties of non-polar molecules. For example, they contribute to the boiling points and melting points of these substances. They also play a role in the solubility of non-polar molecules in non-polar solvents.

In summary, molecular dispersion is a weak intermolecular force that occurs between non-polar molecules. It is caused by temporary fluctuations in electron distribution and increases with the size of the molecule. It is responsible for the physical properties of non-polar substances.
