View answer and explanation
Correct option: D
I−>Br−>Cl−>F−{\mathrm{I}^ - } > B{\mathrm{r}^ - } > \mathrm{C}{\mathrm{l}^ - } > {\mathrm{F}^ - }
Option D (I−>Br−>Cl−>F−{\mathrm{I}^ - } > B{\mathrm{r}^ - } > \mathrm{C}{\mathrm{l}^ - } > {\mathrm{F}^ - }) is correct because reducing power increases down the group due to increasing size and decreasing electron gain enthalpy.
