A) \[{{F}_{2}}>C{{l}_{2}}>B{{r}_{2}}>{{I}_{2}}\]
B) \[C{{l}_{2}}>{{F}_{2}}>B{{r}_{2}}>{{I}_{2}}\]
C) \[B{{r}_{2}}>C{{l}_{2}}>{{F}_{2}}>{{I}_{2}}\]
D) \[{{I}_{2}}>B{{r}_{2}}>C{{l}_{2}}>{{F}_{2}}\]
Correct Answer: B
Solution :
The electron affinities of halogens is as: \[C{{l}_{2}}>{{F}_{2}}>B{{r}_{2}}>{{I}_{2}}\] Fluorine has lesser value of electron affinity than chlorine due to its smaller size and higher electron density.You need to login to perform this action.
