For alkanes side chains the positions of side chains or alkyl substituents are indicated by lowest numeral places before prefix.
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 on the basis of
The Fischer projection is written along with the priorities assigned and groups are interchanged between adjacent places so as to obtain lowest priority group at the bottom or lowest priority.
If the groups now are arranged are read from highest towards least in clockwise fashion the R is assigned to the stereocenter, if the rotation is anticlockwise the S is assigned at the configuration.

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 on the basis of atomic number. The one with 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 lowest priority group at the bottom or lowest priority.
If the groups now are arranged are read from highest towards least in clockwise fashion the R is assigned to the stereocenter, if the rotation is anticlockwise the S is assigned at the configuration.
