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) Londondispersion | (c) $1\over r^3$ |
| (d) $1\over r^6$ |
(1) (i) – (a); (ii) – (b); (iii) – (c)
(2) (i) – (a); (ii) – (b); (iii) – (d)
(3) (i) – (b); (ii) – (d); (iii) – (c)
(4) (i) – (a); (ii) – (c); (iii) – (d)
