WebIt is not the case that Z and cis or E and trans are always interchangeable. Consider the following fluoromethylpentene: The proper name for this molecule is either trans-2-fluoro-3-methylpent-2-ene because the alkyl groups that form the backbone chain (i.e., methyl and ethyl) reside across the double bond from each other, or (Z)-2-fluoro-3 ... WebSo basically, Z is just a fancy way of saying cis with three or more substituents. E is a fancy way of saying trans with 3 or more substituents. Using the periodic table to assign priorities, trans = E, and cis = Z . Example #1: Assign an (E) – (Z) designation to the following alkenes if applicable. Example #1: Assign an (E) (Z) designation ...

WebEarlier we looked at cis- and trans-isomers in square planar platinum complexes. Other transition metal complexes display cis-trans isomerism. Octahedral complexes can also have two particular ligands adjacent to each other or on opposite sides of the metal atom.
