The main difference between cis and trans isomers is that cis isomers are essentially polar whereas trans isomers are comparatively nonpolar. Key Areas Covered. 1. What are Cis Isomers â Definition, Properties in Relation to the Structure 2. What are Trans Isomers â Definition, Properties in Relation to the Structure 3.
E-and Z-nomenclature of alkenes On the previous pages, we looked at naming alkenes as cis-and trans-. Misconception Alert! cis Â¹ Z and trans Â¹ E. In general terms there is NO specific relationship between cis and trans / E and Z as they are based on fundamentally different naming rules.he Cahn-Ingold-Prelog priority rules are used for naming geometric isomers (e.g. E-or Z-alkenes) and other stereoisomers (see later). These rules are based on atomic number, and the first point of difference.
