WebThe terms cis-trans isomerism or geometric isomerism commonly are used to describe configurational isomerism in compounds with double bonds and rings. When referring to the configuration of a particular isomer, we mean to specify its geometry. 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.
