The energies of interaction for (i) ion pair, (ii) ion-dipole, and (iii) dipole-dipole interactions are inversely proportional to
(a)$r, r^{2}$ and $r^{3}$ respectively
(b)$r^{2}, r$ and $r^{3}$ respectively
(c)$r, r^{2}$ and $r^{6}$ respectively
(d)$r^{2}, r$ and $r^{6}$ Respectively
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
Ion–ion energy ∝ 1/r, ion–dipole ∝ 1/r², dipole–dipole (fixed orientation) ∝ 1/r³ (rotating dipoles average to 1/r⁶).
