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. Webof chirality in organic molecules is a tetrahedral atom, most commonly carbon, bonded to four different groups. • A carbon with four different groups bonded to it is called a chiral center. – All chiral centers are stereocenters, but not all stereocenters are chiral centers. – Enantiomers:: Stereoisomers that are nonsuperposable mirror ...
