Carbon & Co. The number of known organic chemical compounds has now exceeded the 100 million mark. Nevertheless, this enormous quantity can be summarized into a few classes of substances with very similar properties. The functional groups of even the most complex molecules are often the same, and examining the principles of reactions quickly reveals that much is repeated, just in different forms. Therefore, anyone who understands the fundamental processes of organic chemical reactions can quickly grasp the compounds. With a good overview, learning becomes much easier. The Beyer/Walter textbook, now in its seventh decade, is the most traditional and - with a quarter of a million copies sold - the most successful German textbook on Organic Chemistry, now appears with a completely new didactic concept.
