Arrange `S,O and Se` in ascending order of electron affinity?

A

`Se lt S lt O`

B

`O lt Se lt S`

C

`S lt O lt Se`

D

`S lt Se lt O`

Text Solution

Verified by Experts

The correct Answer is:
B
On moving down in the group `EA` decreases but due to smaller size of oxygen incoming electoron experience more repulsion so `EA` of `O` is less then S.
`S gt O gtSe`.
