Answer 2

Match the following, proportionality with distance according to their interaction energy.

species interaction

interaction energy proportionality

(i) ion - ion (a) ∝ 1/r

(ii) dipole - dipole (b) ∝ 1/r²

(iii) London dispersion (c) ∝ 1/r³

(d) ∝ 1/r⁶

solution : according to Coulomb's law,

Energy between two ions is proportional to 1/r².

i.e., (i) ⇒(a)

Potential energy between parallel dipoles is proportional to 1/r³.

so, (ii) ⇒(c)

for London dispersion, interaction Energy is proportional to 1/r⁶

(iii) ⇒(d)

Therefore the correct option is (1) (i) -> a , (ii) -> c , (iii) -> (d)
