Which is the correct order of second ionization potential of C , N , O and F in the following ?
Options
- AO > N > F > C
- BO > F > N > C
- CF > O > N > C
- DC > N > O > F
Correct answer
B. O > F > N > C
Step-by-step solution
The second ionization potential means removal of electron from cation C ⁺=1 s^2 2 s^2 2 p^1, ~N ⁺=1 s^2 2 s^2 2 p^2 O ⁺=1 s^2 2 s^2 2 p^3, ~F ⁺=1 s^2 2 s^2 2 p^4 Therefore O > F > N > C
