Chemistry Question on Classification of elements & periodicity in properties

The correct order of electron affinity of halogens is

A

F>Cl>Br>IF>Cl>Br>I

B

I>Br>Cl>FI>Br>Cl>F

C

Cl>F>Br>ICl>F>Br>I

D

Cl>F<Br<ICl > F < Br < I

Answer

Cl>F>Br>ICl>F>Br>I

Explanation

Solution

The order of electron affinity of halogens is as Cl>F>Br>ICl > F > Br > I FF has lesser value of electron affinity than ClCl. It is due to smaller atomic size of FF.
