Web1. Introduction Many organic substances are chiral molecules, which can exist as levo and dextrorotatory optical antipodes. These molecular entities being mirror images of each other and non-superposable are called enantiomers. 1 In their molecular structures, enantiomers possess a chiral element, which in most cases is a chiral center and less frequently, a … WebMay 5, 2024 · 2 Steps to Follow When Looking for Chiral Centers in Molecules. 1. Eliminate atoms that cannot be chiral centers. A chiral center is a stereocenter with an atom (usually carbons) attached to four nonidentical substituents. To spot potential chiral centers in a molecule, look for carbons connected to four different groups.
