The correct order of electron affinity of B, C, N, O is – InterviewSolution

1.	The correct order of electron affinity of B, C, N, O is
Answer» `O gt C gt N gt B` `B gt N gt C gt O` `O gt C gt B gt N` `O gt B gt C gt N` Solution :`underset(140.9)Ogtunderset(122.3)Cgtunderset(83)Bgtunderset(0)N` Values of ELECTRON affinity increases on going from left to right in periods but the value of electron affinity of `V^(th)` A elements is less than that of `IV^(th)` A ELEMENT, this is due to half filled p-orbital present.
