Cis-trans isomerism in alkenes

WebCis / trans isomerism occurs where two of the atoms or groups of atoms attached to each carbon atom of the C=C bond are the same E / Z isomerism is an example of stereoisomerism where different atoms or groups of atoms are attached to each carbon atom of the C=C bond Cis / trans isomers WebJun 11, 2015 · Explanation: In E −Z isomers you must have: restricted rotation, often involving a C=C double bond two different groups on one end of the bond and two different groups on the other end. For example, an alkene such as but-2-ene has two different groups on each alkene carbon.
