It works because all organic molecules will have different boiling points, An ester or haloalkane has a different BP to other substance in the impure mixture. The liquid with the lower BP will start to boil at a lower temp, evaporate and move down the condenser where it is cooled and returns to liquid state. It will then turn to a vapour and rise to above where a condenser is attached. The Flash-based versions of these tutorials are no longer available. At the end of the reaction different techniques are needed in order to separate the products from the reaction mixture, and then the final compound will need to be purified by means of specific operations.
