What is the bond order of CO?

This Free PDF Notes contains Bond order of CO Molecule is for upcoming government exams. In addition, The bond order of the CO molecule is 3. Bond order is a measure of the number of chemical bonds between two atoms in a molecule and is calculated using the number of bonding electrons and antibonding electrons. In the CO molecule, the carbon atom has 4 valence electrons and the oxygen atom has 6 valence electrons. The carbon and oxygen atoms form a single bond, which involves 2 bonding electrons. There are no antibonding electrons, so the bond order of the CO molecule is 3. We endure that molecular orbital theory( MOT) explains the conformation of atoms, which also helps in adjudicating the bond ordering of the atoms.

  • The bond order of CO molecule on the basis of molecular orbital theory is :
    • 1
    • Zero
    • 3
    • 2
    • None of the above
      • The correct answer is 3.

The bond order of co molecule is 3. Bond order is delineated in chemistry science as the distinctiveness between the opus of bonds and anti-bonds, as substantiated by Linus Pauling. The opus of electron dyads( covalent bonds) between two molecules is the bond opus. For illustration, the total number of bonds between diatomic nitrogen NN is 3, the number of bonds between the two carbon molecules in ethyne HCCH is 3, and the bond order of CH molecule is 1.

A bond’s sturdiness is adjudicated by its number of bonds. The number of bonds of isoelectronic classification is the indistinguishable. The number of bonds may not subsist an numeral in atoms with resonance or nonclassical adhesion.

Bond order in CO

Here is the molecular orbital (MO) energy level diagram for the CO molecule: Bond order of CO Molecule is

In this MO energy level diagram, the horizontal axis represents the energy of the MOs, with the lowest energy MOs at the left and the highest energy MOs at the right. The vertical axis represents the number of electrons that can occupy each MO. The filled circles represent electrons, with the number of circles indicating the number of electrons. The lines connecting the circles represent the MOs. The bonding MOs are shown in blue, while the antibonding MOs are shown in red.

The HOMO and LUMO of the CO molecule are the bonding and antibonding molecular orbitals formed from the overlap of the 2s orbitals of the carbon atom and the 2p orbitals of the oxygen atom. The CO molecule has a bond order of 3, which means that it has 2 chemical bonds between the carbon and oxygen atoms. The bond order can be calculated using the formula: bond order = (number of bonding electrons – number of antibonding electrons)/2.

Molecular orbital energy level diagram of CO molecule
  • CO molecule has 10 valence electrons, four from carbon atom (2s²2p²) and six from oxygen atom (2s²2p⁴).According to molecular orbital diagram, molecular orbital configuration is given as
  • σ2s² σ*2s² πx² πy² σz² π*x⁰ πy⁰ σ*z⁰
  • Thus , bond order = 1/2(8–2)=3
