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...
Consider the molecule shown below. ch_2ohchohchohch_3, Indicate chiral centers and predict the total number of stereoisomers. Draw them out in the Fischer projection. Build a model of one of them (orient it in the Fischer projection) so you can visualize the shape and how the chain curves. Sketch it to the best of your ability. Which of the molecules are enantiomers of each other? Are there any meso compounds? Justify your answers and draw them out. Take a pair of...
