The dipole-dipole interaction energy between polar molecules in the solid state will be proportional to ...... [if r denotes the distance between polar molecules]

Options

  1. A1 r^6
  2. B1 r^3
  3. C1 r^2
  4. D1 r

Correct answer

B. 1 r^3

Step-by-step solution

Dipole-dipole interaction energy between polar molecules in solids depends on the distance between them as per following relation. Dipole-dipole interaction energy 1 r^3 ( r= radius on the molecule under consideration) Hence, the correct option is (2).
