Question

The decreasing order of electron affinity is: (A) F > Cl > Br > I (B) Cl > F > Br > I (C) I > Br > Cl > F (D) Br > Cl > F > I

On moving down the group, electron affinity decreases due to increase in size but Cl shows higher electron affinity than fluorine due to vacant d -orbitals.

Q. The decreasing order of electron affinity is:

$F > Cl > B r > I$

$Cl > F > B r > I$

$I > B r > Cl > F$

$B r > Cl > F > I$

On moving down the group, electron affinity decreases due to increase in size but Cl shows higher electron affinity than fluorine due to vacant $d$ -orbitals.

Q. The decreasing order of electron affinity is:

F>Cl>Br>I

Cl>F>Br>I

I>Br>Cl>F
