WebFeb 21, 2024 · A Chiral Center is an atom that has 4 different group bonds. These group bonds are in such a way that it has a non superimposable mirror image. It is also called a chiral atom, chiral center, or chirality. It is a stereocenter that has a set of atoms in such a way that the structure cannot be superimposed on its mirror image. WebJul 20, 2024 · There are two types of stereoisomers: enantiomers and diastereomers. Enantiomers are pairs of stereoisomers which are mirror images of each other: thus, A and B are enantiomers.
