2-bromobutane (3.0 ml) in 25 ml of acetone reacts with 80 ml of a 20 wt% solution of Nal in acetone. After work up, you obtain 3.9 g of 2-iodobutane. What is the limiting reagent and percent yield of this reaction? Why when finding the mass of Nal in acetone do you use the density of acetone and not Nal?
