Addition of an electron to an antibonding molecular orbital

Options

  1. Aincreases bond order
  2. Bdecreases bond order
  3. Cstabilises the system
  4. Ddecreases the inter-nuclear distance

Correct answer

B. decreases bond order

Step-by-step solution

Bond order = Number of bonding electrons - Number of antibonding electrons 2 Addition of an electron to an antibonding molecular orbital results in overall decrease in bond order.
