Khan Academy: Boiling Points of Organic Compounds

Have you ever wondered why cities in cold climates put salt on the roads to help keep ice from forming? In this chemistry video, Sal explains why the introduction of salt molecules suppresses, or delays, the formation of ice crystals...

How to analyze the different boiling points of organic compounds using intermolecular forces. [11:06]

Understand what happens when raising or lowering the boiling or freezing point of a solution by adding solute. [14:00]

Practice comparing the boiling point of nonane and 2,3,4-trifluoropentane. A sample multiple choice problem from the 2014 AP Chem course description. [6:19]

Boiling point elevation is the raising of a solvent's boiling point due to the addition of a solute. Similarly, freezing point depression is the lowering of a solvent's freezing point due to the addition of a solute. In fact, as the...
