a complex MO diagram: B2H6 MO diagrams combine two fragments. Symmetry fragments . these are MOs from C2H4 which belongs to the D2h point group. Ethene C2H4 molecular orbitals.
Using MOLCAS I calculated the MO’s of ethene to see the sp2 hybridisation and to observe the pi and pi*. Loop Diagram.

C2H4. Ethene from above the trigonal plane. The carbon atoms and orbitals are.
Many molecular orbital diagrams are not made up from atomic orbitals, but from fragment molecule (C2H4) is like the dxz AO and hence has b2g symmetry. Ethylene is the simplest molecule that has a double bond.
As we saw from the valence bond model, we should find the presence of a σ-bond framework, and a .where E is the energy of the molecular orbital. is the coefficient in the molecular orbital of the atomic wavefunction from the i-th atom. is the overlap integral between atoms i and j: (Note that the diagonal elements are equal to unity: since the atomic orbitals are normalised) and finally.
π Molecular Orbitals of Ethene. In chapter 1 we saw that the molecular orbitals of H 2 are created by the combination of 1s orbitals.; The in-phase combination gave the bonding orbital.
The out-of-phase combination the anti-bonding orbital. ORBITALS and MOLECULAR Construct the molecular orbital diagram for dichlorine.
