When writing the IUPAC name of a molecule, each R and S designation can be written immediately before the first number used to locate the substituent attached to the asymmetric carbon atom. An alternate way is to write all the R and S designations together at the front of the name. The locator number for each asymmetric carbon atom must appear before its R or S designation and the designations must be separated from each other by a comma.
(b)
Interpretation:
Each asymmetric carbon in the given molecule is to be assigned R or S configuration.
Concept introduction:
The four groups attached to an asymmetric carbon are assigned priorities on the basis of the atomic number of the atom that is directly attached. In the case of a tie, the atoms one bond away are compared. If the priority groups 1 to 3 are arranged clockwise with the lowest priority group at the back, the asymmetric carbon is assigned an R configuration. If they are arranged counterclockwise, the configuration is S.
