Question
In which of the following ionization processes, the bond order has increased and the magnetic behaviour has changed?
Choose an option
Show full solutionCorrect option: B
Correct answer
B
Step-by-step explanation
In electron is removed from bonding molecular orbital so bond order decreases. In , electron is removed from anti bonding molecular orbital so bond order increases and nature changes from paramagnetic to diamagnetic.
Hence, (B) is correct.
