The absolute configuration of molecules depicted should be written. Concept introduction: In order to assign absolute configuration of R and S Cahn − Ingold − Prelog rules are used and the first step is to assign the priority order with the atomic number as the fundamental property. The one with the highest atomic number gest highest priority and is designated as “a” and so on. The Fischer projection is written along with the priorities assigned and groups are interchanged between adjacent places so as to obtain the lowest priority group at the bottom or lowest priority. If the groups now are arranged are read from highest towards least in clockwise fashion then R is assigned to the stereocenter if the rotation is anticlockwise the S is assigned at the configuration. Any organic compound must have no plane of symmetry in order to be optically active. The compounds with any plane of symmetry are achiral and optically inactive.
