What is meant by the term bond order? Explain.
(N/A) Bond order is defined as one half of the difference between the number of electrons in bonding molecular orbitals $(N_{b})$ and the number of electrons in antibonding molecular orbitals $(N_{a})$.
The formula is: $\text{Bond Order} = \frac{1}{2} (N_{b} - N_{a})$.
Significance:
$1$. $A$ positive bond order $(N_{b} > N_{a})$ indicates a stable molecule.
$2$. $A$ negative or zero bond order $(N_{b} \leq N_{a})$ indicates an unstable molecule or that the bond is not possible.
