WebbAlkanes can’t have geometric isomers (cis/trans isomers) because they can rotate around the C-C single bond. Because of this movement, it doesn’t stay in one configuration (cis or trans) thus, it cannot have geometric isomers. Which type of isomerism is shown by alkanes? Structural isomerism WebbGeometric Isomers: compounds with the same type and number of atoms and the same chemical bonds but different spatial arrangements; such isomers cannot be interconverted without breaking a chemical bond Unsaturated Hydrocarbons: hydrocarbons that contain carbon-carbon double bonds or carbon-carbon triple bonds Addition Reaction: a reaction … immigration renewal onlineWebbTo get geometric isomers you must have: restricted rotation (often involving a carbon-carbon double bond for introductory purposes); two different groups on the left-hand end of the bond and two different groups on the right-hand end. immigration renewal canada

WebbAlkenes 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.
