Solution
The correct option is Brs<rl<rg The correct relation between the intermolecular distances rs,rlandrg in solids, liquids and gases respectively is rs<rl<rg. Solids have strong intermolecular forces of attraction. Hence, they are the closest. The intermolecular forces of attraction are weakest in gases and therefore, they are farthest apart.
