_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.
