WebApr 9, 2016 · This is a molecule of cumulene, C4H 4. Single bonds are one σ -bond, while double bonds are one σ and one π -bond. σ and π -bonds are just ways in which electron orbitals interact to form bonds - σ are stronger bonds, but you can't have more than one between the same two atoms. Cumulene has three double bonds and four single … WebMar 26, 2024 · But the Jahn-Teller theorem says that such geometries must distort, and further that that distortion will split the degeneracy, and so the HOMO is no longer degenerate. In the case of cyclobutadiene the splitting is so large that the lower of the states is double occupied, hence no ESR signal. – Ian Bush.
