The course companion of choice for a generation of chemistry students. Emphasis is on understanding rather than learning facts: organic chemistry emerges as a coherent whole, with numerous logical connections and consequences, and with anunderlying structure and language. Emphasis on mechanism, orbitals, and stereochemistry means that the student emerges with solid understanding of important factors common to all reactions, allowing interpretation/prediction of reactions not previously met. Direct, personal, student-friendly writing style draws in and engages the reader, motivating them to learn more. Extensive online support takes learning beyond the printed book, enhancing understanding still further.
