In this experiment, you compared the efficacy of simple distillation to the efficacy of a fractional distillation for the separation of 2-butanone from toluene. What is the primary difference between the apparatus used in fractional distillation as compared to simple distillation? Based on this information, explain how one might alter the apparatus used in distillation in order to provide a very clean separation between two substances with very similar boiling points. (Repeating the distillation multiple times is NOT a viable option.)
