The dipole-dipole interaction energy between polar molecules in the solid state will be proportional to ...... [if \(r\) denotes the distance between polar molecules]
- A \(\frac{1}{r^6}\)
- B \(\frac{1}{r^3}\)
- C \(\frac{1}{r^2}\)
- D \(\frac{1}{r}\)
Answer & Solution
Correct Answer
(B) \(\frac{1}{r^3}\)
Step-by-step Solution
Detailed explanation
Dipole-dipole interaction energy between polar molecules in solids depends on the distance between them as per following relation. Dipole-dipole interaction energy \(\propto \frac{1}{r^3}\) ( \(r=\) radius on the molecule under consideration) Hence, the correct option is (2).
