WebApr 15, 2015 · The FMO diagram for benzene thus looks like a Frost circle. This way of thinking also leads to anti-aromatic configurations which explain why cyclobutadiene cannot exist, and why cyclooctatetraene forces itself out of planar configuration in order to avoid an unfavorable state: WebVideo transcript. We have seen that a compound or ion is aromatic if it contains a ring of continuously overlapping p orbitals, and also if it has 4n plus 2 pi electrons in the ring, where n is an integer. So for example, n could be 0, or 1, or 2, or so on. We can use these criteria to analyze the cyclopropenyl cations.
