Frost Diagram Aromaticity. To construct a frost diagram proceed as follows. It allows one to find the number of molecular orbitals in the molecule s π system and their energetic positions.

How to use frost diagrams to predict the relative molecular orbital energies of aromatic and antiaromatic compounds. Cyclobutadiene has non bonding mos. Frost circles for five membered rings cyclic 5 membered pi systems with 6 pi electrons are predicted to be aromatic.
As orgo 2 lectures start up there will be a number of concepts that will be covered quickly to speed up the class so you can learn lots of functional group transformations this semester.
So the correct diagram should look like total energy 2 α 2β 2α 4α 4β. Benzene 6 electrons non bonding level for aromatic compounds such as benzene. Aromatic 4n 2 frost diagram. Such non bonding mos are not present in aromatic systems like benzene.
