For C,N,O and F, which of the following ...

For `C,N,O and F`, which of the following orders is correct for `IP`?

A

`FgtOgtCgtN`

B

`OgtFgtNgtC`

C

`FgtNgtOgtC`

D

`NgtFgtOgtC`

Text Solution

Verified by Experts

The correct Answer is:
C
On moving left to right in period due to increase in `ENC` ionisation potential increase. But `N` has half-filled p-subshell (stable) so it has more ionisation potential than oxygen.
`:. F gt N gt O gt C`.
