The electron affinities of halogens are \[F=322\], \[Cl=349\], \[Br=324\], \[I=295kJ\,mo{{l}^{-1}}\]. The higher value for \[Cl\] as compared to that of \[F\] is due to [MP PMT 1997]

A. Weaker electron-electron repulsion in \[Cl\]
B. Higher atomic radius of \[F\]
C. Smaller electronegativity of \[F\]
D. More vacant P - subshell in \[Cl\]
Answer» B. Higher atomic radius of \[F\]
