A molecule with one chiral center has a three-dimensional structure where the chiral center is a carbon atom bonded to four different substituents. The spatial arrangement of these substituents around the chiral center gives rise to stereoisomers, specifically enantiomers.Enantiomers are non-superimposable mirror images of each other, like left and right hands. They have the same molecular formula and connectivity of atoms but differ in the spatial arrangement of the substituents around the chiral center. The relationship between enantiomers can be described using the Cahn-Ingold-Prelog CIP priority rules and assigning R or S configuration to the chiral center.To assign R or S configuration:1. Assign priority to the four substituents around the chiral center based on their atomic number higher atomic number gets higher priority .2. Arrange the molecule in a way that the lowest priority substituent usually hydrogen is pointing away from you.3. Determine the order of the remaining three substituents 1, 2, and 3 in a circular manner.4. If the order is clockwise, the configuration is R rectus ; if counterclockwise, the configuration is S sinister .The enantiomers of a molecule with one chiral center will have opposite configurations R and S at the chiral center. They have identical physical and chemical properties, except for their interaction with plane-polarized light and chiral environments e.g., biological systems, chiral catalysts . One enantiomer will rotate plane-polarized light to the right dextrorotatory, + , while the other will rotate it to the left levorotatory, - . In chiral environments, enantiomers may exhibit different reactivity, which is crucial in pharmaceuticals and other applications where stereochemistry plays a significant role.
