The electron affinity of halogens are \( \mathrm{F}=322, \mathrm{Cl}=349, \mathrm{Br}=324, \mathrm{I}=295 \mathrm{~kJ} \mathrm{~mol}^{-1} \). The higher value for \( \mathrm{Cl} \) as compared to that of \( \mathrm{F} \) is due to:
(AIIMS 2012)
P
(a) weaker electron-electron repulsion in \( \mathrm{Cl} \)
(b) higher atomic radius of \( \mathrm{F} \)
W
(c) smaller electronegativity of \( \mathrm{F} \)
(d) more vacant \( p \)-subshell in \( \mathrm{Cl} \)
