Addition of an electron to an antibonding molecular orbital

  1. A increases bond order
  2. B decreases bond order
  3. C stabilises the system
  4. D decreases the inter-nuclear distance
Verified Solution

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.
