The correct order of the second ionisation potential of carbon, nitrogen, oxygen and fluorine is

A

`C gt N gt O gt F`

B

`O gt N gt F gt C`

C

`O gt F gt N gt C`

D

`F gt O gt N gt C`

Text Solution

Verified by Experts

The correct Answer is:
C
The ionization potential increases across the period but the second ionization potential of oxygen is highest among them because after the removal of `1e^(-)`, the `2e^(-)` is to be removed from half filled orbital which is difficult.
