Webcis-trans and E-Z are just different naming systems for the same thing. stereoisomers in when two molecules are non-superimposable mirror images of each other, whereas two … WebTranscribed image text: When we name alkenes, the configurations cis and trans are used only if there are two identical groups, one on each vinylic (sp2) carbon. The configurations E and Z can be used for all alkenes. In most cases cis = Z and trans = E. But there are exceptions. Name this alkene.
