Title: Use of the E-Z Notation in Cis-Trans Isomerism Description: This multimedia article proposes and applies the rules for assigning the E-Z notation to geometric isomers. Llorens Molina, JA. (2014). Use of the E-Z Notation in Cis-Trans Isomerism. http://hdl.handle.net/10251/38107 Automatic description: This video explains the use of the Z notation in cis-trans isomerism, describing the relationship between the two and how the notation is applied using the Cahn-Ingold-Prelog rules. It highlights that when similar substituents on an alkene double bond are on the same side, it is considered a cis or Z configuration, while if they are on opposite sides, it is trans or E. The video then details how to apply these rules when the substituents are different. Priority is determined by the atomic number of the atoms directly connected to each carbon in the double bond. In the event of a tie, the chain of atoms is followed until a difference is found. For the purposes of assigning priority, a double or triple bond is considered equivalent to multiple bonds to the same atom. Finally, practical examples are shown to illustrate how substances are correctly named using these rules. Several molecular structures are analyzed, identifying priority substituents and assigning the corresponding E or Z configuration to each double bond, resulting in the appropriate systematic nomenclature for each alkene example presented.
