Question

CHEM 3401 PreLaboratory Assignment, Elimination Reactions of Alkyl Halides, day 2 Due at the beginning of the lab period. Reading Assignment from Zubrick, 9th ed.: Reflux, pp. 201-202; Elimination Reactions of Alkyl Halides Experiment, GSU Laboratory Manual 1. What purpose does the water in the Hempel column/condenser serve in the reflux setup? The purpose of the water in the Hemper column] ondenser is too cool vapors before they leave the system, which maintains volume and induces reaction 2. You are performing the elimination with potassium tert-butoxide and tert-butyl alcohol. At what temperature will the reaction mixture begin refluxing? 3. In this experiment, two elimination reactions are performed with the same substrate, 2- chloro-2-methylbutane, and two different bases. a. Draw the two possible elimination products. Then indicate which base is needed to produce each one as the major organic product. ΝαΟΗ TBUOK b. Provide an explanation for the difference in the two reactions.
