Match the type of interaction in column A with the distance dependence of their interaction energy in column B
A B
(i) ion-ion (a) 1r{1 \over r}
(ii) dipole-dipole (b) 1r2{1 \over {{r^2}}}
(iii) London dispersion (c) 1r3{1 \over {{r^3}}}
(d) 1r6{1 \over {{r^6}}}

Multiple Choice Options

  • A (I)-(a), (II)-(b), (III)-(d)
  • B (I)-(b), (II)-(d), (III)-(c)
  • C (I)-(a), (II)-(b), (III)-(c)
  • D (I)-(a), (II)-(c), (III)-(d)

Step-by-Step Verified Solution

Ion-ion interaction energy ∝\propto 1r{1 \over r}

Dipole-dipole interaction energy ∝\propto 1r3{1 \over {{r^3}}}

London dispersion ∝\propto 1r6{1 \over {{r^6}}}
