The London force, also known as dispersion force, is a type of intermolecular force that arises from the fluctuation of electron distribution in molecules. This force is present between all types of molecules, including non-polar ones that do not have a permanent dipole moment. The interaction energy of London force between two particles is inversely proportional to the sixth power of the distance between them. However, the magnitude of this force depends upon the polarisability of the interacting particles.
Polarisability of interacting particles
Polarisability is a measure of how easily the electron distribution in a molecule can be distorted by an external electric field. The more easily a molecule's electron cloud can be distorted, the higher its polarisability. This property is related to the size, shape, and electronic structure of the molecule. Molecules with larger electron clouds and more electrons tend to have higher polarisabilities.
Importance of polarisability in London force
In the case of London force, the interaction energy between two particles arises from the temporary fluctuations in their electron clouds. These fluctuations can induce a temporary dipole in one particle, which then induces a dipole in the other particle. The strength of this induced dipole and hence the interaction energy depends upon the polarisability of the particles. The higher the polarisability, the easier it is for the electron cloud to be distorted and hence the stronger the induced dipole and the interaction energy.
Thus, the correct answer to the given question is option 'D', i.e., the magnitude of London force depends upon the polarisability of interacting particles.
