By this process trans-2-pentenenitrile can be separated from a mixture containing mainly 3-pentenenitrile by isomerizing the trans-2-pentenenitrile to cis-2-pentenenitrile and removing the more volatile cis isomer by fractional distillation.
Ring structures or cyclic compounds can also exhibit cis/trans isomerism without the presence of a pi bond. Remember, substituents will be cis and trans if they arelockedin place. Pi bonds are one way to lock them in place. Rings are another matter. For example,in 1,2-dimethylcyclohexane,...

Benzene molecules with fluoro- and trifluoromethyl-substituents have been used to sensitize the cis–trans isomerization of but-2-ene in the gas phase at 25 °C and various exciting wavelengths. For most compounds studied, the decay ratio of the olefin triplet to cis- and trans-ground-states ...
Why are optical isomers not found for CH_2ClBr? Which of the following is capable of exhibiting cis-trans isomerism? a. 1-butene b. 1-pentene c. cyclohexene d. 2-butene Explain why an alkyne often has a slightly higher boiling point than an alkene of similar molecular weight....
At pressures greater than 40 Torr, the quantum yield for cis → trans isomerization is 0.50 ± 0.02. An isomer (probably ethylcyclopropane) as well as some of the pentene-1 are formed by intramolecular hydrogen-atom migration, followed by collissional stabilization. The steady-state ratio [...
Trans-stilbene is a solid whereas cis-stilbene is a liquid. What might be a reason for this difference in physical property? Explain why cis-1-chloro-2-methylcyclohexane undergoes E2 elimination much faster than its trans isomer. What really causes the trans-boundary pollution?
