Divide by 2.
Upon getting calculated the online variety of bonding pairs, you may calculate the bond order by dividing the online variety of bonding pairs by 2.
The components 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 that 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 that the bond is a double bond, as a result of a double bond has a bond order of two.
And so forth.
Upon getting calculated the bond order, you need to use it to foretell the properties of the molecule, reminiscent of its stability and reactivity.
For single bonds, bond order is 1.
