Solution
Verified by Toppr

The London dispersion force is the weakest intermolecular force. It is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.
Hence non-polar and electrically symmetrical atoms can develop London dispersion forces between them.

Q5
The intermolecular forces operating between two constituent particles depends on the distance between the centres of the molecules. Dipole-dipole interactions are inversely proportional to 3rd power of the distance whereas dipole-induced dipole interaction are inversely proportional to the sixth power of intermolecular distances.
