2) a) Consider 2-bromo-3-chlorobutane. How many stereoisomers are possible for this compound? Draw all stereoisomers, label each stereocenter with the appropriate R/S designation to show handedness, and indicate the relationship (enantiomers or diastereomers) between every possible pairing of compounds. Name each compound according to IUPAC nomenclature, using appropriate R/S designation to show handedness. b) Repeat this exercise for 2,3-Butanediol. What is different about this compound relative to the first example? What word describes the unique stereoisomer? c) Which of the...
