Assigning Priorities: Examples of Naming Compounds

Name the following molecules using the proper stereochemical orientations. The base name of each molecule will be provided for you.

Base name: 7-bromo-2-chloro-4-methyl octane

As shown above, the orientations of the stereocenters in this molecule are S (at the chlorine stereocenter), S (at the methyl stereocenter), and R (at the bromine stereocenter). Therefore, the complete name for this molecule is (7,R)-bromo-(2,S)-chloro-(4,S)-methyl octane.
