22) Hexahelicene, an aromatic compound, seems to be a poor candidate for optical activity because all of its atoms are sp2 hybridized and presumably flat. This compound has a very high calue for its specific rotation, la p= 3700. Explam wy hexahelicene is optically active.
19-26 thanks! 19-29* 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...
