A fractional bond order is possible in molecules and ions that have resonance structures. In the example of ozone, the bond order would be the average of a double bond and a single bond or 1.5 (3 divided by 2).
The same formula is applied to calculate the bond order. It is the value which tells about whole or fractional number.
