“We have used a number of editions of Loudon for our second year organic course. Although each edition has represented a major advance in the presentation of new chemistry, they have all retained the lucid presentation and order of topics that attracted us to the first version. The problems and examples provide excellent reinforcement of the contents of each chapter. The inclusion of modern methodology in the newest edition will prepare students for graduate school and demonstrates the continuing evolution of organic chemistry.” —Robert H. Grubbs, California Institute of Technology

“My colleagues and I have used the Loudon text here at Harvard for a number of years. The latest edition of this textbook refines the author's approach to the teaching of organic chemistry on a mechanism-based approach that was first introduced by Cram and Hammond more than 50 years ago. I consider it one of the premier texts of this generation.” —David Evans, Harvard University

“This text continues to refine the author's characteristically elegant, mechanism-based framework for introducing organic chemistry. Professor Loudon has inspired several generations of students with his clear and insightful presentation style. In no other text does the logic, power and sheer beauty of organic chemistry shine through so clearly.”  —Bruce Ganem, Cornell University

“This book is simply marvelous. It has plenty of stimulating illustrations and examples, and its many problems progress gradually from trivial to challenging and instructive. But, most importantly, its exposition is rock-solid, full of the lucid analogies and consistent mechanistic logic that make organic chemistry tractable.”  —AMAZON (a student at Caltech)

“From over thirty years in the classroom, Marc Loudon knows how students learn. His problems are the work of a master teacher; they are original, range in difficulty levels, and are all based on real examples from the literature. This edition is clearly a labor of love and reflects Professor Loudon’s desire to give students the very best learning tool possible. This book is a symphony of great ideas and will open students’ eyes to the wonders of modern organic chemistry.” —John Grutzner, Purdue University
