Question

What are London forces in chemistry?

Answer 1

See below.

Explanation:

London dispersion forces are considered the weakest intermolecular type of Van der Waals forces.

They are present in an instantaneous electric dipole moment in non-polar as well as polar molecules.

This type of force becomes stronger as the atom enlarges, and to a smaller degree for large molecules. This is due to the increased polarizability of molecules with more dispersed electron clouds where free electrons can be found.
