Chirality and Stereoisomers - Chemistry LibreTexts

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. WebI would identify this as a Carl center, so I put a red star here. The next carbon. It is double bonded to on oxygen, and like I said earlier, we need to have four different groups. But since that is not the case for this particular carbon, it is not a Carl center moving on. We have oxygen that can't be a Carl center.
