CHCH(OH)-CH(OH)-CH3 PART 3: 23-BUTANEDIOL 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. fill in the remaining hydrogen atoms. Remember, a model is not different if it is completelv superimposable on one already constructed! 13. How many stereochemically different models are possible for 2.3-butanediol? 14. What characteristic does one of these models have that makes it different?...

rojection Formulas for each model in #16 (again orient the carbon chain up and down). Are the mirror images "superimposable?" Interchange any two of the groups located at one of the chiral centers on one of the models in # 1 6. What is the stereochemical relationship of the resulting structure with the one that used to be its mirror image? Will this 'new' model be "optically active?" Why or why not? 18.
