View answer and explanation
Correct option: C
I−,Br−,Cl−,F−{\mathrm{I}^ - },\mathrm{B}{\mathrm{r}^ - },\mathrm{C}{\mathrm{l}^ - },{\mathrm{F}^ - }
Option C (I−,Br−,Cl−,F−{\mathrm{I}^ - },\mathrm{B}{\mathrm{r}^ - },\mathrm{C}{\mathrm{l}^ - },{\mathrm{F}^ - }) is correct because polarizability increases with size. Larger ions are more easily polarized.
