WebCis-trans isomers have different physical, chemical, and physiological properties. Cis -2-butene has both methyl groups on the same side of the molecule. Trans -2-butene has the methyl groups on opposite sides of the molecule. Their structural formulas are as follows: Figure 3 : Models of (left) Cis-2-Butene and (right) Trans-2-Butene. WebMay 20, 2024 · Would it be correct to say that they are cis-trans isomers of each other. I have understood that if a ring has two substituents on the same side of the ring plane, it's called a trans isomer (eg. trans-1,2-dichlorocyclohexane) and if they are on different sides, it's called a cis isomer (eg. cis-1,2-dichlorocyclohexane).
