This texts clear explanations and descriptions of the mechanisms of chemical reactions teach students how to apply principles in order to predict the outcomes of reactions. The Fifth Edition offers a focus on biological applications that renders the text accessible to the majority of organic chemistry students and consistent with the interdisciplinary nature of scientific research.One Small Step features apply familiar concepts to new reagents and reactions, encouraging students to analyze material rather than memorize the outcome to each new reaction.Visualizing the Reaction features help students recognize important reactions by demonstrating the complete mechanisms for each type of reaction. HM ClassPrep with HM Testing CD-ROM includes lecture outlines and line art from the textbook in PowerPoint, the Computerized Test Bank and the Word files of the Test Bank in a new, easy-to-use interface with complete cross-platform flexibility, electronic versions of materials from the Instructors Resource Manual, and a transition guide that directs instructors through this new edition.
