"WebOct 19, 2024 · The way I was taught to find stereoisomers was to count the number of double bonds that can be E / Z and the stereocentres, and do 2 n. There are no stereocentres, and no double bonds, so the number of stereoisomers would only be 1 (only one molecule). This disagrees with the cis -/ trans -isomers number which would be 2.

WebCis-trans isomers can occur when atoms or functional groups are situated on either end of a rigid carbon-carbon bond, such as a double bond. In this case, restricted rotation about the double bond means that the atoms or groups attached to either end can exist in one of two possible configurations.
