Question

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 r (ii) Dipole - dipole (b) 1 r 2 (iii) London dispersion (c) 1 r 3 (iv) 1 r 6

TestHub · Accepted Answer

(i) ion-ion interaction energy is inversely proportional to the distance between ions $(\frac{1}{r})$
(ii) dipole-dipole interaction energy is inversely proportional to the third power of $r (\frac{1}{r^{3}})$
(iii) The interaction energy of London force is inversely proportional to sixth power of distance between two interaction particles $(\frac{1}{r^{6}})$

A	B
(i) ion - ion	(a) $\frac{1}{r}$
(ii) Dipole - dipole	(b) $\frac{1}{r^{2}}$
(iii) London dispersion	(c) $\frac{1}{r^{3}}$
	(iv) $\frac{1}{r^{6}}$
