WebChirality is an important geometric property relating to a molecule's symmetry. A chiral molecule is non-superimposable with its mirror image, and has a "handedness" (think of shoes, which specifically go with a right or left foot). WebSep 9, 2024 · Locate the chiral or stereogenic center. Assign priority to each group based on the atomic number of the atom attached to the center, where 1 = high and 4 = low. Determine the direction of priority for the other three groups, in order of high to low priority (1 to 3). If the order is clockwise, then the center is R.

WebPlanar 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.
