Question

The electron affinities of halogens are F=322, Cl=349, Br=324, I=295$kJmo{l}^{-1}$. The higher value for Cl as compared to that of F is due to

• 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 1

The correct option is A

Weaker electron-electron repulsion in Cl

The electron affinities of halogens are F=322, CI=349, Br=324, I=295$kJmo{l}^{-4}$. The higher vlaue for CI as compared to that of F is due to
