Cis - trans isomerism
WebCis/trans isomers. In 1,2-dichloroethene Table 1, however, restricted rotation about the double bond means that the relative positions of substituent groups above or below the double bond become significant.This leads to a special kind of isomerism. The isomer in which the two chlorine (Cl) atoms lie on the same side of the molecule is called the cis … WebThe cis- and trans- isomers cannot be judged by just looking at the isomers. This is because all the substituents attached to the carbon-carbon double bond are different, there aren’t any obvious things that we can think of as being “cis” or “trans” to each other.
