Even though all living things have a lot in common, different organisms can have very different reactions to the same organic chemicals. That means it’s really important for organic chemists to be able to purify chemicals and separate the products we want from reactions, from the side products we don’t. In this episode of Crash Course Organic Chemistry, we’re heading into the lab to learn about one of the ways we can separate chemicals in a mixture: chromatography! Episode Sources: Mahdi, J. G.
