The primary focus of this book was to craft a textbook catering to students, aiming to convey the intricacies of Organic Chemistry in a straightforward and conceptual manner. Our goal is to enable students to comprehend the subject by reasoning through the material, rather than relying on rote memorization of numerous facts with the hope of not exceeding their memory capacity. We firmly believe that a solid understanding of the 'why' in Organic Chemistry significantly enhances the grasp and retention of the 'what.' The book is organized into four units, each commencing with a concise one-page overview, complemented by multiple sections to provide students with a clear roadmap of their learning journey. \n \nSalient features: \nUnit-1: Basic understanding of Organic Chemistry \nUnit-2: Nomenclature of Organic Compounds \nUnit-3: Study of Isomerism \nUnit-4: Electronic effects and its applications.
