Question

8.
The electron affinities of halogens are F = 322, CI = 349,
Br = 324 , I = 295kJ mol-1. The higher value for Cl as
compared to that of F is due to
(a) Weaker electron-electron repulsion in CI
(b) Higher atomic radius of F
(c) Smaller electronegativity of F
(d) More vacant p-subshell in CI​

Answer 1

Answer:

(a) option is correct

Explanation:

ELectron affinity of Cl is more as compared to F because chlorine have more space to put an electron and fluorine accept better electron (F have higher electro negativity) but donot have enough space to put an electron and the electron if put in fluorine so it got more repulsion as compared to chlorine .

That's why electron affinity in Chlorine is more than Fluorine.
