The process requiring the absorption of energy is

A

`FrarrF^(-)`

B

`ClrarrCl^(-)`

C

`OrarrO^(2-)`

D

`HrarrH^(-)`

Text Solution

Verified by Experts

The correct Answer is:
C
The second I.E. is greater than first I.E. similarly second E.A. is greater than first E.A. the energy is to be supplied to force the second `e^(-)` into the anion.
