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).
