Anti aromatic compounds are those compounds which have 4n pi electrons and are conjugated systems. They are usually unstable. This deems your question wrong in the first place. Resonance is not something that acts like a oscillating or moving electron game as many of them usually generalize it too. It is the inability of us to predict a single correct ...

It turns out this question has some subtleties. The analysis presented below, based on Huckel MO theory, indicates that: 1. The compound as presented by the OP is not expected to be aromatic and would be anti-aromatic by the Huckel model -- meaning in practice it would probably distort out of full conjugation to avoid this calamity. 2. The dication, ...

Corannulene (which is rather planar, the angle between adjacent C6 rings are small) is not a good comparison, as it is just a helicene-type C6 polycycle that forms a ring, basically coronene cut one ring short. A simple molecule with structural similarity is https://en.wikipedia.org/wiki/Azulene and it is indeed aromatic. However I guess the two additional ...
