Question

1. Consider the following table of solubilities for a new compound you have synthesized and want to purify by recrystallization. Explain which solvent would be the best choice and explain why the other three would be less suitable.

                               solubility of compound in 100 mL solvent

solvent                   at 25 C                   at BP of solvent

ethanol                     2g                               3g

chloroform                6g                               7g

hexane                     4g                               15g

toluene                     14g                             18g

Explanation / Answer

answer.The suitable solvent may be hexane because solubility of unknown is less at room temperature and more at the BP of the solvent.where as for other solvents solubilityof unknown is less at BP of solvent (there isno more change in solubility).
