A student test two solvents (A and B) for purification an impure organic compound. It is found that the compound has low solubility in both of solvents at low temperature and soluble at boiling point. If solvent A has a lower vapor pressure compare to B. Then: O Only A could be used for recrystallization of this compound. O None of both solvents could be used for recrystallization of this compound. O Both solvents could be used for recrystallization of this compound with the preference for B. O Both solvents could be used for recrystallization of this compound with the preference for A. Only B could be used for recrystallization of this compound.
