The electron affinities of halogens are $F = 322$,$Cl = 349$,$Br = 324$,$I = 295 \ kJ \ mol^{-1}$. The higher value for $Cl$ as compared to that of $F$ is due to
- AWeaker electron-electron repulsion in $Cl$
- BHigher atomic radius of $F$
- CSmaller electronegativity of $F$
- DMore vacant $p-$subshell in $Cl$
