图书简介
Organic chemistry can be a challenging subject. Most students view organic chemistry as a subject requiring hours upon hours of memorization. Author David Klein’s Second Language books prove this is not true-organic chemistry is one continuous story that actually makes sense if you pay attention. Offering a unique skill-building approach, these market-leading books teach students how to ask the right questions to solve problems, study more efficiently to avoid wasting time, and learn to speak the language of organic chemistry. Covering the initial half of the course, Organic Chemistry as a Second Language: First Semester Topics reviews critical principles and explains their relevance to the rest of the course. Each section provides hands-on exercises and step-by-step explanations to help students fully comprehend classroom lectures and textbook content. Now in its fifth edition, this valuable study resource covers the characteristics of molecules, the nature of atomic bonds, the relationships between different types of molecules, drawing and naming molecules, and essential molecular reactions.
