WebAlkenes and cycloalkanes are structural isomers of each other. Give an example of each using C4H8. Another common feature of alkenes and cycloalkanes is that both have restricted rotation about one or more bonds in the compound, so both can exhibit cis- trans isomerism. What is required for an alkene or cycloalkane to exhibit cis-trans isomerism? WebCycloalkanes with substituents on two or more carbons of the ring show a type of isomerism called cis-trans isomerism. Cis-trans isomers isomers that have the same connectivity of their atoms but a different arrangement of their atoms in space due to the presence of either a ring or a carbon-carbon double bond. functional group WebMay 1, 2024 · Cis-trans isomerism(Often called geometric isomerismalthough this term refers to all stereoisomers) is a form of stereoisomerism and describes the orientation of functional groups at the ends of a bond around which no rotation is possible.
