The second edition of the book continues to offer a range of pedagogical features maintaining the balanced approach of the text. The attempts have been made to further strengthen the conceptual understanding by introducing more ideas and a number of solved problems. Comprehensive in approach, this text presents a rigorous treatment of organic chemistry to enable undergraduate students to learn the subject in a clear, direct, easily understandable and logical manner. Presented in a new and exciting way, the goal of this book is to make the study of organic chemistry as stimulating, interesting, and relevant as possible. Beginning with the structures and properties of molecules, IUPAC nomenclature, stereochemistry, and mechanisms of organic reactions, proceeding next to detailed treatment of chemistry of hydrocarbons and functional groups, then to organometallic compounds and oxidation–reduction reactions, and ending with a study of selected topics (such as heterocyclic compounds, carbohydrates, amino acids, peptides and proteins, drugs and pesticides, dyes, synthetic polymers and spectroscopy), the book narrates a cohesive story about organic chemistry. Transitions between topics are smooth, explanations are lucid, and tie-ins to earlier material are frequent to maintain continuity. The book contains over 500 solved problems from simple to really challenging ones with suitable explanations. In addition, over 275 examples and solved problems on IUPAC nomenclature, with varying levels of difficulty, are included.
