Answer:
London Dispersion forces are a part of wan-der-vals forces. The instantaneous dipole–induced dipole attractions are called London dispersion forces.
London’s dispersion force < dipole-dipole < H-bonding < Ion-ion
London dispersion forces are the weakest intermolecular force.
The unequal distribution of electrons about the nucleus in an atom induces a dipole in the atom. When another atom or molecule comes in contact with this induced dipole, it can be distorted and leads to an electrostatic attraction between atoms or molecules.
