WebJan 3, 2015 · A molecule is considered chiral if there exists another molecule that is of identical composition but which is arranged in a non-superposable mirror image. Also the presence of an asymmetric carbon atom is often the feature that causes chirality in molecules. Two mirror images of a chiral molecule are called enantiomers or optical … WebR and S are used to describe the configuration of a chirality center. Chirality center meaning that there are 4 different groups attached to one carbon. To determine whether the chirality center is R or S you have to first prioritize all four groups connected to the chirality center. Then, rotate the molecule so that the fourth priority group ...

WebStereochemistry focuses on stereoisomers. In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space.
