The boiling points of ethanol and ethanal are 78.37 degrees C and 20.2 degrees C respectively. Explain the reason for this variation in the boiling points of these two compounds with similar molecular weights. Discuss intermolecular attractions between t The ...
Distillation is the process of separating components based on their different boiling points. Reflux is the return of process fluid after it has been cooled, condensed, heated or boiled. The two processes use similar equipment.
There are two kinds of boiling points — dry boiling point and wet boiling point. The dried boiling point is determined by using the fluid from a brand new container. On the other hand, the wet boiling point is determined by using a fluid that has been contaminated by 3.7% water. The ...
