Easy MCQ +4 / -1 PYQ · JEE Mains 2020

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) ${1 \over r}$
(ii) dipole-dipole (b) ${1 \over {{r^2}}}$
(iii) London dispersion (c) ${1 \over {{r^3}}}$
(d) ${1 \over {{r^6}}}$

  1. A (I)-(a), (II)-(b), (III)-(d)
  2. B (I)-(b), (II)-(d), (III)-(c)
  3. C (I)-(a), (II)-(b), (III)-(c)
  4. D (I)-(a), (II)-(c), (III)-(d) Correct answer

Solution

Ion-ion interaction energy $\propto$ ${1 \over r}$ <br><br>Dipole-dipole interaction energy $\propto$ ${1 \over {{r^3}}}$ <br><br>London dispersion $\propto$ ${1 \over {{r^6}}}$
