Organic chemistry is required coursework for degrees in life, food, and medical sciences. To help the students discouraged by the belief that this topic cannot be mastered without significant memorization, Arrow Pushing in Organic Chemistry serves as a handy supplement for understanding the subject.• Includes new chapters, an expanded index, and additional problem sets complete with detailed solutions• Focuses on understanding the mechanics and logic of organic reaction mechanisms• Introduces ionic and non-ionic reactive species and reaction mechanisms• Teaches strategies to predict reactive species, sites of reactions, and reaction products• Provides a solid foundation upon which organic chemistry students can advance with confidence
