Water is polar --> immersible with organic matter
Fractional distillation helps to separate organic mixture which boiling points are greater than certain difference.
I seldom heard of something called burned away in fractional distillation, if you do not burn and vaporize the liquid until reaching the boiling point, how can it become gas and liquefy in cooler compartment and be being extracted?
