Because of orbital degeneracy at this energy level, the two electrons remain unpaired, as dictated by the Hund rule, making the molecule paramagnetic in spite of its even number of electrons. Sign in to download full-size image Figure 3. Molecular orbital energy diagram for oxygen diatomic ...

Energy level diagram for a heteronuclear diatomic molecule AB. Interaction between the 4σ+ and 5σ+ levels may push 5σ+ above 1π. Suppose n = 0,1,2 is the number of electrons in a nondegenerate molecular orbital Ψ. In the LCAO approximation (26.4-7)ψ=caφa+cbφb and (26.4-8...
I thought I understood the molecular orbital theory but this practice question is making me confused. 1. For a diatomic molecule of oxygen (O2), we define the bond as lying along the z axis. a) Draw the valence MO diagram for O2. Include labels for molecular orbitals. ...
Energy φ– = N–(A–B) anti-bonding R R φ+ = N+(A+B) bonding φ– is more anti-bonding Energy φ– = N–(A–B) φ– is more anti-bonding than φ+ is bonding anti-bonding R E1s φ+ = N+(A+B) bonding Summary MO theory is another orbital approximation but it uses LCAO...

In the MO diagram, the antibonding electrons occupy a higher energy slot than the bonding electrons.What Is Molecular Orbital Theory? The molecular orbital theory, (or MO theory) explains chemical bonding and the delocalization of electrons in molecules. The valence electrons do not just occupy ...

Molecular Orbital Theory The number of molecular orbitals (MOs) that can be formed must equal the number of atomic orbitals of the combining atoms In MO theory we construct the orbital interaction diagram first and then put in the electrons according to the aufbau principle AB A-B A-B* ...
