The process requiring the absorption of energy is

A

`F rarr F^(-)`

B

`C rarr Cl^(-)`

C

`O rarr O^(2-)`

D

`H rarr H`

Text Solution

Verified by Experts

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