Addition of an electron to an antibonding molecular orbital
- A increases bond order
- B decreases bond order
- C stabilises the system
- D decreases the inter-nuclear distance
Answer & Solution
Correct Answer
(B) decreases bond order
Step-by-step Solution
Detailed explanation
Bond order = Number of bonding electrons \(\frac{- \text { Number of antibonding electrons }}{2}\) Addition of an electron to an antibonding molecular orbital results in overall decrease in bond order.
