Reaction Mechanisms in Organic Chemistry is specially designed for the students preparing for medical & engineering competitive exams as well as for the students of undergraduate chemistry honours/major programmes to understand the mechanism of various organic reactions, functional group transformations and synthetic methods. 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. The book comprises Section-I Theories and Basis of Reaction Mechanism. It also consists of Section II Alphabetically arranged Named Reactions, Rearrangements & Reagents. Each concept in the book is theoretically well explained with a lot of solved practice problems covering all levels of questions from basic to advanced, and all types of questions with only one correct option, more than one correct option, assertion-reason type, comprehension type, match the columns, etc. With the help of this book, students will be able to organise and inter-relate the facts about a reaction supported by experimental evidence.
