If you conducted this experiment using (R) 2-bromobutane, what would be the stereochemistry of the product? How, if at all, would the stereochemistry of the product differ if the sodium iodide had not been included in the reaction mixture? This is the experiment: Formation of n-Butyl Acetate Just Below Reflux Set up a sand bath on a magnetic stirrer— start on “4” until it reaches 100°C To a 5-mL long-necked round-bottomed flask, add 0.750 g of sodium acetate trihydrate (NaOAc...
QUESTION: Write a flow scheme for the work-up. THE WORK UP: C. Work-up (save all layers) and Isolation of Product MgBrCl Benzoic acid Transfer the mixture into a test tube. Rinse the beaker with about 3 mL of regular (not anhydrous) diethyl ether and pour the washings into the test tube. There should be two distinct layers in the test tube Remove the aqueous layer (to be discarded) and shake the ether layer with about 2 mL of 3 M...
