How to Calculate Bond Order?

Go through the detailed steps to calculate the bond order of the chemical bond between antibonding electrons & bonding electrons.

  • Check the number of bonding electrons, antibonding electrons.
  • Subtract the antibonding electrons from the bonding electrons.
  • Divide the difference by 2 to obtain the order of bonding.

Bond Order Definition | Valence Bond Theory

The bond order finds the stability of a molecule or ion. The higher bond order means stronger is the bond and higher bond energy. We have several definitions for bond order.

The valence bond theory states that the number of bonded electron pairs between two atoms is the bond order.

In molecular orbital theory, the bond order is defined as half of the difference between the number of bonding electrons and the number of antibonding electrons.

Let us consider some of the examples of bond order using valence bond theory

The bond order of O2 oxygen molecule is 2 as it is a double bond

Oxygen Bond Order

The bond order of NO3: It has four bonds & three bond groups in nitrate

Nitrate Bond Order

Bond order = number of bonds/number of groups

= 4/3 = 1.33

Bond Order Formula | Molecular Orbital Theory

In molecular orbital theory, the bond order can be calculated using the function that describes the state of an electron in the particle. Those functions are called orbitals. The orbitals represent the locations of electrons in the electron cloud.

The bond order formula is given here:

Bond Order = (Number of bonding electrons - Number of antibonding electrons)/2


Question: Find the bond order of hydrogen gas, H2?


The electronic configuration of hydrogen is (σ1s)2

Bond Order = (Number of bonding electrons - Number of antibonding electrons)/2

= (2 - 0)/2

= 1

Therefore, the bond order of hydrogen gas is 1. has got concepts like physical chemistry, stoichiometry, atom, molarity, cell EMF, concentration and many more along with their relevant calculators all one under one roof.


Frequently Asked Question's Calculator Bond Order
