Molecular Orbital Theory • For example, when two hydrogen atoms bond, a σ1s (bonding) molecular orbital is formed as well as a σ1s* (antibonding) molecular orbital. • The following slide illustrates the relative energies of the molecular orbitals compared to the original atomic orbitals. • Because the energy of the two electrons is lower Simple Molecular Orbitals - Sigma and Pi Bonds in Molecules An atomic orbital is located on a single atom. When two (or more) atomic orbitals overlap to make a bond we can change our perspective to include all of the bonded atoms and their overlapping orbitals. Since more than one atom is involved, we refer to these orbitals as molecular orbitals. Benzene is a clear, colorless, highly flammable and volatile, liquid aromatic hydrocarbon with a gasoline-like odor. Benzene is found in crude oils and as a by-product of oil-refining processes. In industry benzene is used as a solvent, as a chemical intermediate, and is used in the synthesis of numerous chemicals.

Benzene is an organic chemical compound with the molecular formula C 6 H 6.The benzene molecule is composed of six carbon atoms joined in a planar ring with one hydrogen atom attached to each. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon.. Benzene is a natural constituent of crude oil and is one of the elementary petrochemicals.

We know that benzene has a planar hexagonal structure in which all the carbon atoms are sp 2 hybridized, and all the carbon-carbon bonds are equal in length. As shown below, the remaining cyclic array of six p-orbitals ( one on each carbon) overlap to generate six molecular orbitals, three bonding and three antibonding.
Molecular Orbital Diagram This is a molecular orbital energy level diagram for the p orbitals. Note that the σ bonding orbital is lowest in energy due to the greater overlap end-onend. σu πg 2p πu σg 2p ... A simplified example will be shown for the π bonding of benzene.
The structure of benzene molecule is best described in terms of molecular orbital treatment theory. According to this theory, all the C-atoms in benzene are sp 2 -hybridized. Two sp 2 -hybrid orbitals of each C-atom overlap with two sp 2 -hybrid orbital of two other C-atoms to form sigma bonds.
The number of pi molecular orbitals in the pi-system equals the number of contributing atomic p orbitals. For butadiene (n=4) we saw that the energy levels of the pi system stacked like a four-story apartment building. Both hexatriene and benzene have six contributing p-orbitals (n = 6), so we should expect six pi orbitals for each.
The orbital structure of benzene: All the carbon atoms in benzene are sp2 hybridised. The three sp2 hybrid orbitals are lying in one plane and oriented at an angle of 120°. The fourth unhybridized p-orbital having two lobes is lying perpendicular to the plane of the hybrid orbital. Two out of the three sp2 hybrid orbitals of each carbon atom overlap axially with sp2 hybrid orbitals of the ...

From the cyclic polyene diagram it can be seen that benzene has six p-molecular orbitals, (which contain the six p-electrons), three bonding and three anti-bonding. The upper bonding degenerate pair of orbitals are the HOMO's of benzene.
Molecular orbital diagram for [Cr(benzene)2] . interaction of the vacant it* ring orbitals with the metal. A more detailed picture of the bonding may be obtained by comparing the electronic charge distribu- tion before and after complexation and for conveni- ence the closed shell CrBz2 molecule will be examined.
Remember: A molecular orbital is the region of space which contains a bonding pair of electrons. Warning! Be very careful how you phrase this in exams. You must never talk about the p orbitals on the carbons overlapping sideways to produce a delocalised pi bond. This upsets examiners because a pi bond can only hold 2 electrons - whereas in benzene there are 6 delocalised electrons.
Note that, like in benzene, when there are multiple ways to represent a combination, one molecular orbital is usually represented to show both bonding and antibonding interactions. The other usually shows the net result, either just bonding or antibonding or, in the case of cyclobutadiene, no direct interaction between adjacent atoms because it ...
