WebDec 19, 2024 · Hexahelicene (and similar molecules) consist entirely of sp2 carbons but are chiral because of steric effects that constrain their overall shape. Then strictly we do not have sp2 hybridization. You have to allow … WebCis and trans double bonds are sterogenic centers in that two different compounds are possible that are stereoisomers (diasteromers). However, that is not sufficient. You must have two cumulated alkenes (c=c bonds next to each other) with at least 2 substituents to have "axial" chirality. There is also helical chirality.
