Cis-trans isomerism of alkenes
WebNov 17, 2024 · It is particularly important that you make molecular models of some simple alkenes to gain insight into the geometry of these compounds. Geometric isomerism (also known as cis-trans isomerism or E-Z isomerism) is a form of stereoisomerism. WebWhat are the cis and trans isomers of alkenes? Do cis and trans isomers have the same structural connectivity? How are cis and trans isomers formed? How are cis and trans isomers used for night vision? How do cis and trans isomers arise in an organic molecule? How do cis and trans isomers arise in cinnamaldehyde?

In a vinylidine molecule the two hydrogens are attached to one carbon while the R-groups are on the other carbon. Vinylidene molecules are not common industrially and will not be discussed further.

WebTraditionally, double bond stereochemistry was described as either cis (Latin, on this side) or trans (Latin, across), in reference to the relative position of substituents on either side of a double bond. A simple example of cis-trans isomerism is the 1,2-disubstituted ethenes, like the dichloroethene (C 2 H 2 Cl 2) isomers shown below.
