Enantiomers are pair of molecules that exist in two forms that are mirror images of one another but cannot be superimposed one upon the other.  They are also referred to by chemists as chiral twins or handed molecules. Each twin is called an enantiomer. Naming of enantiomers is important to understand ‘which structure refers to which enantiomer?’. The chirality of organic molecules is described by the Cahn-Ingold-Prelog (CIP) system. This system is also referred to as the R/S convention … Continue reading Naming enantiomers: the left-(or right-) handed?
