Reaction Mechanisms in Organic Chemistry is primarily written for the students of undergraduate chemistry honours/major programmes to elucidate the sequence of various organic reactions. It will also be useful for first-year postgraduate students in chemistry and those preparing for competitive examinations such as GATE, JAM, and CSIR-UGC NET. Comprising sixteen chapters, the book deals with various commonly encountered organic reaction mechanisms in topics such as organic acids and bases, stereochemistry, reactive intermediates, addition, elimination, and substitution reactions. The last chapter of the book focuses on topics such as esterification, Hammet equation, and tautomerism. Illustrative and student-friendly, this book will be of immense help to students in organizing and inter-relating facts about a reaction supported by experimental evidences, and is ideal for self-study.
