WebA chirality center is also called a chiral center or an asymmetric center. Some sources use the terms stereocenter , stereogenic center , stereogenic atom or stereogen to refer exclusively to a chirality center, [15] [17] [19] while others use the terms more broadly to refer also to centers that result in diastereomers (stereoisomers that are ... WebIntroduction: Planar chirality, like axial chirality, employs the descriptors P (plus) and M (minus). Chiral molecules having atoms a, b and x lying ina plane and y-z in a plane with atom z orthogonal to the plane fall into this category (Fig. 1). Implicit in this description is that z is restricted from lying in the plane.
