A discovery experiment designed for the first semester organic chemistry laboratory course will be presented. Students identify three unknown organic solvents by measuring boiling points of pure liquids and their mixtures and performing miscibility tests. The experiment teaches students the important concepts of intermolecular forces, vapor pressure, boiling point, distillation, and azeotrope. The procedure requires a very simple set up and three common organic solvents as the only chemicals. Detailed experimental protocol, sources of error, and experiment video will be presented.
