Problem 7 : Calculate the bond order for the nitrogen molecule (N₂) using molecular orbital theory.
Solution :

The bond order (BO) is calculated using the formula: BO = (Number of Bonding Electrons - Number of Antibonding Electrons) / 2

In the molecular orbital diagram for N₂, you’ll find:

  • Number of bonding electrons: 10
  • Number of antibonding electrons: 2

BO(N₂) = (10 - 2) / 2 = 4 / 2 = 2

So, the bond order of the nitrogen molecule (N₂) is 2, indicating a triple bond.
