JEE MAIN - Chemistry (2020 - 2nd September Evening Slot - No. 14)
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) $${1 \over {{r^6}}}$$ |
(I)-(a), (II)-(b), (III)-(d)
(I)-(b), (II)-(d), (III)-(c)
(I)-(a), (II)-(b), (III)-(c)
(I)-(a), (II)-(c), (III)-(d)
Explanation
Ion-ion interaction energy $$ \propto $$ $${1 \over r}$$
Dipole-dipole interaction energy $$ \propto $$ $${1 \over {{r^3}}}$$
London dispersion $$ \propto $$ $${1 \over {{r^6}}}$$
Dipole-dipole interaction energy $$ \propto $$ $${1 \over {{r^3}}}$$
London dispersion $$ \propto $$ $${1 \over {{r^6}}}$$
