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) $${1 \over {{r^6}}}$$

The size of a raw mango shrinks to a much smaller size when kept in a concentrated salt solution. Which one of the following processes can explain this?

The one that is not expected to show isomerism is :

Simplified absorption spectra of three complexes ((i), (ii) and (iii)) of Mn⁺ ion are provided below; their $$\lambda $$_max values are marked as A, B and C respectively. The correct match between the complexes and their $$\lambda $$_max values is
(i) [M(NCS)₆]^{(–6 + n)}
(ii) [MF₆]^{(–6 + n)}
(iii) [M(NH₃)₆]ⁿ⁺
