MCQ
The correct order of second ionization potential of carbon, nitrogen, oxygen and fluorine is
- A$C > N > O > F$
- B$O > N > F > C$
- ✓$O > F > N > C$
- D$F > O > N > C$
✓
Answer
Correct option: C.
$O > F > N > C$
c
(c) The ionization potential increases across the period but the second ionization potential of oxygen is highest among them because after the removal of $1$${e^ - }$ the $2$${e^ - }$ is to be removed from half filled orbital which is difficult.
