exaplanation of cyclobutadiene resonance - Science Forums
Posted September 27, 2005. To explain why cyclobutadiene is not aromatic requires one to talk about molecular orbitals, unfortunately, since resonance, conjugation and aromaticity are based on molecular orbital theory. Basically, the four p-orbitals on each of the four carbon atoms will form four Pi orbitals, a bonding orbital, two non-bonding ...
