WebE–Z configuration, or the E–Z convention, is the IUPAC preferred method of describing the absolute stereochemistry of double bonds in organic chemistry. It is an extension of cis – trans isomer notation (which only describes relative stereochemistry) that can be used to describe double bonds having two, three or four substituents . WebThey are geometric isomers and can be labelled as cis or trans in a similar way as disubstituted cycloalkane. Cis / trans is the common designation for geometric isomers and might be ambiguous for some structures. Here, we will learn the IUPAC naming system for the geometric isomers of alkene, which is the E/Z naming system. E/Z Naming System

WebIn addition, trans–alkenes are generally more stable than cis-alkenes, so we can predict that more of the trans product will form compared to the cis product. However, certain other eliminations (which we will not be studying) favor the least substituted alkene as the predominant product, due to steric factors. Such a product is known as the ...
