ORGANIC CHEMISTRY, Ninth Edition, is a student-friendly, cutting-edge introduction for chemistry, health and biological sciences majors. The authors revised the text to align pedagogically with the way your students approach complicated material. In addition to featuring unified mechanistic themes, focused problem-solving, applied pharmaceutical problems and biological examples, the new edition takes a step-by-step approach to reaction mechanisms, emphasizing similarities among mechanisms using four traits: breaking a bond, making a new bond, adding a proton and taking a proton away. The text also includes organic chemistry reaction roadmaps organized by chapter to help your students devise their own reaction pathways. Emphasizing practical “how-to” skills, the new edition is packed with challenging synthesis problems, medicinal chemistry problems and unique roadmap problems, with hundreds of detailed solutions to all in-chapter exercises to guide your students through logical approaches to solving problems of various types. New point-by-point summaries at the beginning of each section highlight important content in a way that is easy for students to review and reference, while in-margin definitions and highlighted integral concepts reinforce key content throughout the text. 100 author-created videos, available in OWLv2, explain and illustrate the most difficult concepts in an engaging way.
