Abstract

The following flow charts and notes provide a step-by-step process for the identification of functional groups that may be present in an unknown sample [1-11]. These are meant to augment and confirm information obtainable using instrumental methods of analysis. It will usually be necessary to use gas or liquid chromatography before these "wet" chemical tests are performed in order to determine the number of components present in a given sample. Since many of these tests require the use of sometimes toxic compounds, the strictest rules of laboratory safety must be observed at all times. The use of a fume hood is often required. The book by Feigl and colleagues is an excellent guide for spot tests [11].
