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.
Natural unsaturated fatty acids are in configuration that is called cis, but partial hydrogenation can flip the chemical bonds into a different configuration that is called trans. The difference between cis and trans is that the two H atoms are on the same side of the double bond (cis), compared to being on opposite sides (trans). This may not seem like much of a difference, but it affects the shapes of the molecules. In a cis configuration, the double bond creates a kink in the fatty acid. In the trans configuration, there is no kink. Therefore, a trans-fatty acid is structurally similar to a saturated fatty acid (which has no kinks, either). The kinks in the molecules determine whether the material is solid or liquid at room temperature.
