In which alkene is e/z isomerism possible
Web5 apr. 2015 · E / Z or cis / trans are not applicable here. In the first case, the B r atom is in the ring plane, the methyl group can be above or below it. You could describe the absolute stereochemistry at the centre bearing the C H X 3 substituent using R or S. In the second case, there's no alkene at all but a disubstituted benzene. WebGeometric Isomers of Alkenes In the discussions about 1,2-dimethylcyclohexane in Chapter 4, we learned that there are two geometric isomers possible for that compound: cis and trans. The restricted C-C bond rotation of the cyclic structure results in the cis or trans isomer of 1,2-dimethylcyclohexane.
