Question

In the formation of CO, the 2s orbital from C and 2p orbital from O could also participate in the formation of σ molecular orbital. Explain why this is possible?

Answer 1

The molecular orbital method (MO) is most evident in its graphical model of the linear combination of atomic orbitals (LCAO). ... When atoms approach the distances of chemical bonds, molecular ones are formed from atomic orbitals (AO). 2. The number of obtained molecular orbitals is equal to the number of initial atomic ones.
