Q. According to MO theory which of the following lists ranks the nitrogen species in terms of increasing bond order :

AIPMTAIPMT 2009Chemical Bonding and Molecular Structure

Solution:

Let us calculate the bond order of all the ions and molecules.
We know that
Bond order $=\frac{\text { no. of bond pairs }-\text { no. of anti bonding pairs }}{2}$
For $N_{2}^{2-}$
Bond order $=\frac{10-6}{2}=2$
For $N _{2}^{-}$
Bond order $=\frac{10-5}{2}=2.5$
For $N _{2}$
Bond order $=\frac{10-4}{2}=3$
