Problem 7.7 Determine the configuration of each of the following as Zor E as appropriate: LOH Y OH (a) (b) (c) (d) Sample Solution (a) One of the doubly bonded carbons bears a methyl group and a hydrogen. According to the Cahn-Ingold-Prelog sequence rules, methyl outranks hydrogen. The other carbon atom of the double bond bears a methyl and a —CH OH group. The-CH2OH group is of higher priority than methyl. Higher (C) — Hzc CH2OH - Higher C(O,H,H) Lower...

PART 3: 2,3-BUTANEDIOL CH-CH(OH)-CH(OH)-CH, mirror images, not superimposable Build as many models of 2,3-butanediol as you can. First, attach two carbons with a single bond. To each carbon add one carbon, one hydrogen, and one oxygen. To complete the structure, Ti the remaining hydrogen atoms. Remember, a model is not different if it is completely superimposable on one already constructed! 13. How many stereochemically different models are possible for 2,3-butanediol? 14. What characteristic does one of these...
