In this classic introductory text, the authors aim to identify the new concepts of organic chemistry, to select the ones that are clearly fundamental to the learning of organic chemistry, and then to build them into a framework of the book. The cornerstone of this framework is that chemical behavior is determined by molecular structure. Each topic is presented fully and clearly at a level appropriate for beginning students. The authors emphasize relationships between the seemingly unrelated facts and theories that students are learning in order to reveal the broad and complex pattern underlying organic chemistry. Where possible, they lead the students to find the pattern themselves, by working problems.
