The intermolecular interaction that is dependent on the inverse cube of distance between the molecules is

Options

A. ion-ion interaction
B. ion-dipole interaction
C. London force
D. hydrogen bond

Answer

A

Explanation

Ion-ion interaction is dependent on the square of distance,i.e.ion-ion interaction `prop(1)/r^(2)`
Similarly, ion-dipole interaction`prop(1)/r^(2)`
London forces `prop(1)/r^(6)` and dipole-dipole interactions
[H-bonds]`prop(1)/r^(3).` Thus, H-bonds being dipole-dipole interactions is dependent on the inverse cube of distance between the molecules.
