12 maj 2017 · The “ s – cis ” is a conformation where both double bonds are on the same side of a sigma bond. Recall that there is free rotation about sigma bonds, so we say, “ s-cis ” and “ s-trans ” to distinguish it from “ cis ” and “ trans ” configurations which are locked.

23 sty 2023 · There are two different conformations of conjugated dienes which are s-cis and s-trans conformations. s-cis is when the double bonds are cis in reference to the single bond and s-trans is when the two double bonds are trans in reference to the single bond. The cis conformation is less stable due to the steric interation of hydrogens on carbon.
23 sty 2023 · The configuration at the left hand double bond is E; at the right hand double bond it is Z. Thus this compound is (1E,4Z)-1,5-dichloro-1,4-hexadiene.
10 sie 2021 · Thus cis - and trans -2-butene are configurational isomers, as are cis - and trans -1,2-dimethylcyclopropane. The terms cis-trans isomerism or geometric isomerism commonly are used to describe configurational isomerism in compounds with double bonds and rings.
