Experiment #8 – properties of Alcohols and Phenols Introduction As has been mentioned before‚ over 20 million organic compounds have been identified. If each substance had to be studied as an entity completely separate from all the other substances‚ the study of organic chemistry as a whole would be impossible; that is to say‚ even more impossible than you currently believe it to be. Fortunately‚ the subject can be organized and it is often organized around the concept of the functional group
