the correct order of electron affinty is

A

`OgtCgtNgtB`

B

`BgtNgtCgtO`

C

`OgtCgtBgtN`

D

`OgtBgtCgtN`

Text Solution

Verified by Experts

The correct Answer is:
C
`underset(140.9)(O)gtunderset(122.3)(C) gt underset(83)(B) gtN` value of electron affinity increase on going from left to right in periods but the value of electrons affinity of `V^(th)` `A` elements is less than that of `IV^(th) A` element, this is due to half-filled p-orbitals presence.
