If you evaluated 5 solvents as possible recrystallization solvents do you think it is generally true that the solvent which appears to dissolve the solute is always the best choice? What about a solvent that does not appear to dissolve the solute at all, should if automatically be eliminated as a potential recrystallization solvent? Give a brief explanation for your reasoning for both the most and least soluble solvent-solute combination of the first five solvents.
