how is the carbon monoxide bond is formed?[explain with figure ] also show the sahring of electrons

                                                Resonating structures of Carbon Monoxide

The molecule's bond length is consistent with a partial triple bond. The molecule has a small dipole moment and can be represented by three resonance structures.The leftmost resonance form is the most important as inferred by reactions of carbon monoxide.The structures above explain the sharing of electrons between carbon and oxygen.Further explaination requires use of molecular orbital theory which is beyond the scope of 10th standard.
