How to determine cis and trans
Web1,2-disubstituted alkenes are described as: cis - if the two alkyl groups, R-, are on the same side of the C=C trans - if the two alkyl groups, R-, are on opposite sides of the C=C. these terms are inserted into the name as prefixes. For example, but-2-ene, where both R = methyl : trans-but-2-ene cis -but-2-ene WebIn the trans configuration, the carbon backbone is more or less linear, whereas in the cis configuration, the backbone contains a bend, or kink. (Some ring-shaped molecules can also have cis and trans configurations, …

WebThe cis,trans-isomer cannot adopt a planar conformation because of steric hindrance between the two phenyl rings. The non-coplanar geometry lowers the efficiency of interactions with the stationary phase, making it more mobile. So the cis,trans isomer has a higher Rf, and the trans,trans isomer has a lower Rf. ... WebThe situation would be different if we were considering two of the same groups bonded to different sides of the alkene. In the example above we can now say that the two butyl groups are either cis or trans to one another, since both sides of the alkene can be distinguished (on each side of the alkene, we can assign a group of higher priority).
