WebDec 11, 2015 · It can therefore form cis and trans isomers. Which of them will be the major product depends upon the stability of the compound. As you can see, in the given conditions there was no mentioning that the compound has to be symmetrical to form cis-trans isomerism. You don't have to look for symmetry, but for the above conditions. Weball terminal alkenes i.e. those with a C=CH 2 unit can not exist as cis- and trans- isomers. similarly, all 1,1-symmetrically disubstituted alkenes i.e. those with a C=CR 2 unit can not exist as cis- and trans- isomers. alkenes with the R 1 -CH=CH-R 2 unit can exist as cis- and trans- isomers.
Cis–trans isomerism can also occur in inorganic compounds, most notably in diazenes and coordination compounds. Diazenes (and the related diphosphenes) can also exhibit cis–trans isomerism. As with organic compounds, the cis isomer is generally the more reactive of the two, being the only isomer that can reduce alkenes and alkynes to alkanes, but f… WebSep 13, 2024 · These two compounds are cis-trans isomers (or geometric isomers), compounds that have different configurations (groups permanently in different places in space) because of the presence of a rigid structure in their molecule.
