Why would a solvent with a very high boiling point be inappropriate for a recrystallization?     Too much solvent would be lost to evaporation during the heating phase of the recrystallization     Impurities and the compound to be recrystallized would dissolve equally well in this solvent     A high boiling solvent would not dissolve the compound to be recrystallized     It would be difficult to remove residual solvent from the purified crystals
