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.

( A to C) Graphical representation of the dihedral angles formed by four atoms: ϕ 35-12-11-22 (red), ϕ 35-17-8-18 (blue), and ϕ 35-13-14-27 (green). A detailed description of the atomic types and numbering of each dihedral angle may be found in fig. S21.

WebIn general, if you have a small molecule with no sp3 centers in the molecule, the molecule is planar. But there are many exceptions. Here are a few common ones: - Water is planar. The oxygen is sp3 but there are only 3 atoms so there's nothing to stick out of the HOH plane. - Allene is not planar.

WebIn chemistry, a molecule or ion is called chiral (/ ˈ k aɪ r əl /) if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called chirality (/ k aɪ ˈ r æ l ɪ t i /).
