1. Briefly describe how a drying agent works. List the names and chemical formulas for five typical drying agents.
2. Elemental bromine (Br2)reacts with 3-hexene to form 3,4-dibromohexane.
a. Write out the balanced equation for this reaction.
b. If 11.5 g of 3-hexene is reacted with 8.8 g Br2, what is the theoretical yield of 3,4- dibromohexane?
c. If you did the reaction described in (c) and isolated 15.9 g of 3,4- dibromohexane, what is the percent yield for the reaction?
