Question 7 :
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 ${3}^{rd}$ power of the distance whereas dipole-induced dipole interaction are inversely proportional to the sixth power of intermolecular distances.<br/><br/>In which of the following the extent of interaction is proportional to $\dfrac{1}{{r}^{6}}$ where ($r =$ intermolecular distance)?
