Figure 26.3 Schematic representation of the formation of two molecular orbitals (bonding and antibonding) by combination of two atomic H(ls) orbitals. The lowering of the energy with respect to that of the atomic orbital level leads to the chemical bond...

Shape and Energy of H2 Molecular Orbitals Bonding and antibonding MOs have different shapes and energies. Figure 11.14 shows these orbitals for H2 ...

In a pi molecular orbital (bonding or antibonding), the electron density is concentrated above and below an imaginery line joining the two nuclei of the bonding atoms. Two electrons in a pi molecular orbital form a pi bond (see Section 10.5). A donble bond is almost always composed of a sigma bond and a pi bond a triple bond is always a sigma bond pins two pi bonds.

Step 2 Use matching valence-shell atomic orbitals to build bonding and antibonding molecular orbitals and draw the resulting molecular orbital energy-level diagram (Figs. 3.31 and 3.32).
