Concept introduction:
Huckel MOs are determined by constructing Frost’s circle. It is a polygon with appropriate number of sides inscribed in a circle with one of the corners at the bottom. A horizontal line is drawn through the center of the diagram. MOs that lie below this line are bonding MOs; those on the line are nonbonding while those above the line are antibonding MOs.

Using the Frost Circle method to outline the molecular orbitals of cyclobutadiene, and identify whether it is aromatic, antiaromatic or non-aromatic. Explain.
Predict the electronic configurations of (a) the benzeneanion, (b) the benzene cation. Estimate the π-bond energy in each case.
Thoroughly describe what is meant when a compound is considered aromatic. In your answer, provide examples and be sure to discuss how Huckel's Rule applies, and what it means to be anti-aromatic versus non-aromatic. When providing specific examples to demonstrate the requirements that you list, describe the delocalized pi electrons and sp2 hybridization. Lastly, why is benzene so special compared to alkenes like cyclohexene....both are 6-carbon atom cycles so are they chemically similar or not really similar at all?
