Organic Chemistry, 4th Edition provides a comprehensive yet accessible treatment of all the essential organic chemistry concepts covered in a two-semester course. Presenting a skills-based approach that bridges the gap between organic chemistry theory and real-world practice, Dr. David Klein makes content comprehensible to students while placing special emphasis on developing their problem-solving skills through applied exercises and activities. This edition is available with the new and improved WileyPLUS—an immersive online environment packed with interactive study tools, strategies, and resources that support different learning styles. Organic Chemistry incorporates Klein's acclaimed SkillBuilder program which supplies a wealth of opportunities for students to develop the key skills necessary to succeed in organic chemistry. Each SkillBuilder contains a solved problem that demonstrates a skill and several practice problems of varying difficulty levels—including conceptual and cumulative problems that challenge students to apply the skill in a slightly different environment. An up-to-date collection of literature-based problems exposes students to the dynamic and evolving nature of organic chemistry and its active role in addressing global challenges. Throughout the text, numerous hands-on activities and real-world examples help students understand both the "why" and the "how" behind organic chemistry.
