In the molecular orbital diagram for a typical homonuclear diatomic molecule (shown below), only one p atomic orbital from each atom participates in a ?-type bonding molecular orbital. Briefly explain why the remaining two p atomic orbitals cannot participate in ?-type molecular orbitals. Also explain why the two molecular orbitals formed from the remaining p atomic orbitals both have the same energy (i.e. why are they degenerate)?below is a chemtour animation on molecular orbitals. section 9 on molecular orbital diagrams for period 2 homonuclear diatomics will be helpful in answering the following questions.
