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. WebGeometric isomers are not possible if we have two similar groups on the same side ... The rotation is restricted due to the presence of pi-bond in alkenes.

WebBecause of the lack of rotation of C=C double bonds these two molecules are different. But they have the same formula so they are isomers. And the atoms are arranged in the same order with the only difference being the spatial arrangement of the bonds - hence Stereo -isomers. So they'll need different names despite both being But-2-ene.
