Adopting a bio-organic emphasis, this updated and revised text on organic chemistry introduces functional groups. This edition includes increased coverage of Carbon 13 spectra, an expanded treatment of conformational effects of molecules, with two sections covering basic geometries of molecules, and new material on transition metal chemistry and carbohydrate metabolism. Worked examples have been added to chapters on synthesis, and end-of-chapter problems have been expanded by more than 200. The text also includes full-color graphics illustrating conformational effects and general stereochemical properties of organic substances.
