Paperback. Condition: New. Print on Demand. This book presents a system of analytical chemistry focused specifically on identifying organic compounds that contain carbon, combined with hydrogen and nitrogen, and in some cases oxygen. The system is evolutionary and is an extension of an analytical system introduced in an earlier volume. The most significant change in this volume is a reduction in the number of genera in Order II compared to Order I, as well as an increase in carefully verified 'specific characterizations' which aid in the identification process. This book presents a major step forward in the field of organic chemistry, aiding both students and professionals alike in identifying and working with organic compounds. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Seller Inventory # 9781332926961_0
