This organic chemistry video tutorial explains how to name esters. It discusses the iupac nomenclature of esters including the common names as well and the rules that go with it. It contains plenty of examples and practice problems including esters with branches and complex substituents plus esters with other functional groups such as alcohols, alkyl halides ketones, and amines. It shows you how to tell which group has more priority and how to count the number of carbon atoms to determine what the parent name of each portion should be. The examples in this video also include benzene rings, diesters, and halides.
