WebMay 1, 2024 · The form in which the substituent hydrogen atoms are on the same side of the bond that doesn't allow rotation is called cis; the form in which the substituent hydrogens are on opposite sides of the bond is called trans. An example of a small hydrocarbon displaying cis-trans isomerism is 2-butene. 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.

WebGeometric isomerism (also known as cis-trans isomerism or E-Z isomerism) is a form of stereoisomerism. This page explains what stereoisomers are and how you recognise the possibility of geometric isomers in a molecule. Further down the page, you will find a link to a second page which describes the E-Z notation for naming geometric isomers. WebThe most likely example of geometric isomerism you will meet at an introductory level is but-2-ene. In one case, the CH 3 groups are on opposite sides of the double bond, and in the other case they are on the same side. Geometric isomerism in cyclic compounds Geometric isomers can only occur where there is restricted rotation about a bond. So far we have …

WebSep 13, 2024 · These two compounds are cis-trans isomers (or geometric isomers), compounds that have different configurations (groups permanently in different places in space) because of the presence of a rigid structure in their molecule.
