1) The partition coefficient (k = concentration in hexane/concentration in water) between hexane and water for solute A is 7.5
What weight of A would be removed from a solution of 10 g of A in 100 mL of water by a single extraction with 100 mL of hexanes? What weight of A would be removed from the same solution by successive extraction with four portions of 25mL of hexanes? How much hexanes would be required to remove 98.5% of A in single extraction?

2) Using curved-arrow formalism write the complete mechanism for the formation of 1,3-dichlorobutane from 1-chlorobutane using AIBN and sulfuryl chloride. Clearly label each step as part of the initiation, propagation, or termination.
