Average Bond Order represents the average number of chemical bonds between a pair of bond elements.

Average Bond Order

Concept #1: Average Bond Order

A single bond has a bond order of 1, a double bond has a bond order of 2, and a triple bond has a bond of 3. 

Larger the Average Bond Order, stronger the bond strength and shorter the length of the bond.

Example #1: What is the average bond order of the sulfur–oxygen bonds within the sulfite ion?

Practice: What is the bond order of the phosphate–oxygen bonds within the phosphate ion, PO43–?
