WebR and S are labels assigned to the stereocenters of a molecule. To easily find the R and S centers, label the four bonded molecules 1 to 4 in order of atomic number. Place the 4 molecule in the back of the chiral center and then in a clockwise (R) or counterclockwise (S) direction label the bonds with atoms 1, 2, 3. WebThe most prevalent chirality centers in organic chemistry are carbon atoms, which have four different groups bonded to them. Chirality Centers other than Carbon. Any atom which has four different groups bonded to it is a chirality center. The more common of these atoms, with which an organic chemist should be familiar, are Si, N and P (note: a ...
