WebFor example, consider the two compounds on the right. Both compound A (1-bromo-1-chloropropene) and compound B ( 1-cyclobutyl-2-ethyl-3-methyl-1-butene) can exist as a pair of configurational stereoisomers (one is shown). How are we to name these stereoisomers so that the configuration of each is unambiguously specified? WebCis-trans notation does not always correspond to E–Z isomerism, which is an absolute stereochemical description. ... Structural isomers are molecules with the same molecular formula, but their atoms have different arrangements or bonds. ... for example : Butane and isobutane have the same number of carbon (C) atoms and hydrogen (H) atoms, ... shutdown classic timer

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. shutdown clean
