KEYNOTES IN Organic Chemistry KEYNOTES IN Organic Chemistry SECOND EDITION This concise and accessible textbook provides notes for students studying chemistry and related courses at undergraduate level, covering core organic chemistry in a format ideal for learning and rapid revision. The material, with an emphasis on pictorial presentation, is organised to provide an overview of the essentials of functional group chemistry and reactivity, leading the student to a solid understanding of the basics of organic chemistry. This revised and updated second edition of Keynotes in Organic Chemistry includes: new margin notes to emphasise links between different topics,colour diagrams to clarify aspects of reaction mechanisms and illustrate key points, anda new keyword glossary. In addition, the structured presentation provides an invaluable framework to facilitate the rapid learning, understanding and recall of critical concepts, facts and definitions. Worked examples and questions are included at the end of each chapter to test the reader s understanding. Reviews of the First Edition this text provides an outline of what should be known and understood, including fundamental concepts and mechanisms. Journal of Chemical Education, 2004 Despite the book s small size, each chapter is thorough, with coverage of all important reactions found at first-year level... ideal for the first-year student wishing to revise and priced and designed appropriately.
