WebCis–trans notation can be used to describe the configuration of a double bond with exactly two substituents and two hydrogens.If the two substituents are on the same side of the double bond, the configuration of the bond is cis.If the two substituents are on opposite sides of the double bond, the configuration of the bond is trans. Created by Jay. WebApr 26, 2024 · Each carbon of the triple bond is considered to be attached to two atoms of carbon. In E/Z nomenclature, E stands for Entgegen which, in German, means opposite.When groups of higher priority are on the opposite sides of the double bond the bond is assigned the configuration E..

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 ...
