MCQ
Which of the order for ionisation energy is correct
- A$Be > B > C > N > O$
- ✓$B < Be < C < O < N$
- C$B < Be < C < N < O$
- D$B < Be < N < C < O$
✓
Answer
Correct option: B.
$B < Be < C < O < N$
b
(b) Ionisation energy increases across the period but due to stable half filled configuration of $VA$ group, its $I.E.$ is more than $VI-A$ group.
