The system for bond order is:
Bond order = (variety of bonding pairs) / 2
For instance, if a molecule has 3 bonding pairs, the bond order is:
Bond order = (3 bonding pairs) / 2 = 1.5
Which means the bond is a single bond, as a result of a single bond has a bond order of 1.
If a molecule has 4 bonding pairs, the bond order is:
Bond order = (4 bonding pairs) / 2 = 2
Which means the bond is a double bond, as a result of a double bond has a bond order of two.
And so forth.
After getting calculated the bond order, you need to use it to foretell the properties of the molecule, comparable to its stability and reactivity.
