Configurational isomerization of cis - and trans -1,2-, 1,3-, and 1,4-dimethylcyclohexanes has been studied on Rh/SiO 2 catalyst in the range of 373–523 K and a hydrogen partial pressure range of 13.3–100 kPa. Temperature has a small effect on the isomerization rate while this rate...
If we go back to our cis/trans practice problems, such as cis and trans 2-butene, you’ll see that we can use the E/Z system here as well. Carbon 2 and 3 each have a methyl group outranking a hydrogen atom. When they are cis, you get Z. When they are trans you get E. A ...

Geometric (cis / trans) isomerism These isomers occur where you have restricted rotation somewhere in a molecule. At an introductory level in organic chemistry, examples usually just involve the carbon-carbon double bond – and that’s what this page will concentrate on. Think about what happens...
A greatly improved resolution of individual trans-18:1 isomers has been reported by capillary GC on a 100 m cyanopropyl polysiloxane (CP-Sil 88) column.
