WebThe cis-trans naming system can be used to distinguish simple isomers, where each carbon of the double bond has a set of identical groups attached to it. For example, in Figure 8.8b, each carbon involved in the double bond, has a chlorine attached to it, and also … WebAlkenes are usually named using cis/trans or E/Z. Syn and anti are reserved to indicate the geometry of addition across a double bond when it undergoes reactions: if two atoms add from the same side of the double bond then it is called syn, and if they add from opposite …

WebExample: but-2-ene. Isomer 1 : Step 1 : split the alkene. Step 2 : assign the relative priorities. The two attached atoms are C and H, so since the atomic numbers C > H then the -CH3 group is higher priority. Step 3 : look at the relative positions of the higher priority groups : same side = Z, hence (Z)-but-2-ene.
