In both molecules the pi symmetry molecular orbitals are the same. The 2p x orbitals on each atom combine to make a pi bonding and a pi antibonding molecular orbital in the xz plane. Perpendicular to these in the yz plane, the 2p y orbitals on each atom combine to make a pi bonding and a pi antibonding molecular orbital. Here is the full molecular orbital diagram for N 2. Molecular Orbital (MO) Theory is the final theory pertaining to the bonding between molecules. In contrast to VSEPR and valence bond theory which describe bonding in terms of atomic orbitals, molecular orbital theory visualizes bonding in relation to molecular orbitals, which are orbitals that surround the entire molecule. The purpose of MO theory is to fill in the gap for some behavior that ... Pi Molecular Orbitals of 1,3,5-Hexatriene. With a single sigma bond separating the pi bonds of 1,3,5-hexatriene it is a conjugated system and some of the pi electron density will be delocalized between each of the C-C bonds, not just those written as double bonds in the Lewis structure. There are six adjacent carbon atoms involved in the pi ... The side-by-side overlap of two p orbitals gives rise to a pi ([latex]\pi[/latex]) bonding molecular orbital and a [latex]\pi[/latex]* antibonding molecular orbital, as shown in Figure 7.7.6.
