Molecular Orbital Theory and Frontier Orbitals for Organic Chemistry: A Practical Guide is a crucial text for students of organic chemistry. This book provides simple, yet quantifiable explanations based on molecular orbital-based reasoning. It seeks to deepen the reader's understanding of long-standing concepts in MO theory, while also formulating new ones through perturbation molecular orbital theory. Written for undergraduates, graduates, and researchers, the book includes many problems with detailed solutions, allowing readers to test their knowledge as they progress through each chapter.The book emphasizes a practical and pedagogical approach, perfected through the authors' extensive teaching experience. It is ideal for those wishing to gain a thorough understanding of molecular orbital theory, from students to seasoned chemists. The text aims to be distinct in its methodology, making it accessible to a wide audience. The inclusion of in-chapter problems helps reinforce learning, ensuring that readers can immediately apply what they have learned. This book serves as an indispensable resource for anyone seeking to master this fundamental aspect of organic chemistry. - Provides clear explanations of the recent concepts and ideas concerning the structure and properties of organic molecules based on molecular orbital theory - Outlines the genesis of the stereoelectronic effect from perturbation theory (the Salem-Klopman equation) and the underlying rules of engagement covering ionic, pericyclic, radical, and photochemical reactions - Includes in-chapter problems with detailed worked solutions to reinforce the main themes in the text
