1. You have synthesized a new compound: the crude product melts at 102-106 C. You spend a little time purifying it and do the melting point again. What range would you expect the m.p. to be for the purified sample? Explain your reasoning briefly.
2. You have a mixture of solids in the ratio of 50:3 for A: B. You are planning to use the technique of recrystallization to purify A and realize that you will first need to determine which solvent or solvent pair would be appropriate. Describe the solubility properties of the solvent that you would want to use, briefly explaining your rationale.
