Arrange the following species in the decreasing order of their bond orders:
- A (I) \(>\) (II) \(>\) (III)
- B (II) \(>\) (I) \(>\) (III)
- C (II) \(>\) (III) \(>\) (I)
- D (III) \(>\) (II) \(>\) (I)
Answer & Solution
Correct Answer
(B) (II) \(>\) (I) \(>\) (III)
Step-by-step Solution
Detailed explanation
( The strength of bond is determined by bond order (BO). Number of electrons in bonding molecular orbital (a) - Number of electrons in \[ \mathrm{BO}=\frac{\text { antibonding molecular orbital }(b)}{2} \]
