For electron affinity of halogens, which of the following is correct?

Options

(a) Br > F
(b) F > Cl
(c) Br > Cl
(d) F > I

Correct Answer:

F > I

Explanation:

The order of electron affinity is
Cl > F > Br > I
Usually this affinity decreases on moving down in a group with increase in size. But ∑A of elmts of III period > II period, because elmts of II period have small size and greater elctrn density so, incoming elctrns suffer a repulsive force.
