What are cis-trans Isomers?
Cis-trans isomers are also known as geometric isomers. They have the same molecular formula but differ in the orientation of atoms or groups. Cis-trans isomerism is commonly observed in compounds with double bonds and in cyclic compounds. In a cis-isomer, functional groups are on the same side of the double bond or cyclic ring. In a trans-isomer, functional groups are on opposite sides of the double bond or the ring. Consider the structural configuration of cis-2-Butene and trans-2-butene in the image given below. Cis-2- butene has the methyl groups located on same side whereas in trans-2-butene the methyl groups on opposite sides.
Epimers
Epimers are a particular kind of stereoisomer, which is an isomer with the same chemical formula but a different spatial arrangement of atoms. To be more precise, epimers are diastereomers subclass that vary in how their single stereocenter (chiral center) is arranged inside the molecule. In this article, we will learn about epimers, examples, epimerization, etc.
