The names of some organic molecules incorporate specific information about stereochemistry using shorthand notation. One such example is (2R,3R)-2-bromo-3-chlorobutane. This name is written following the nomenclature rules established by IUPAC (International Union of Pure and Applied Chemistry). These rules specify the punctuation to be used in writing the name of a molecule. Write this name exactly as it appears above. (Note: You will not be able to italicize the "R" labels, but you should match exactly the punctuation in the rest of the name.)
