London dispersion forces
London dispersion forces (LDF, also known as dispersion forces, London forces, instantaneous dipole–induced dipole forces, Fluctuating Induced Dipole Bonds or loosely as van der Waals forces) are a type of force acting between atoms and molecules that are normally electrically symmetric; that is, the electrons are ...

are caused by an uneven distribution of electrons within an atom. This results in a slightly negative ( ) and slightly positive charge on either side of the atom. A temporary dipole has been established. This temporary dipole can induce a temporary dipole on a neighbouring atom/molecule.

How are LDFs made?

The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. ... Dispersion forces are present between any two molecules (even polar molecules) when they are almost touching.

How are dipole forces formed?

Dipole -dipole interactions occur when the partial charges formed within one molecule are attracted to an opposite partial charge in a nearby molecule. Polar molecules align so that the positive end of one molecule interacts with the negative end of another molecule.
