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.  The fifth edition o_f Organic Chemistry as a Second Language: Second Semester Topics_ builds upon the principles previously explored in first half of the course--delving deeper into molecular mechanisms, reactions, and analytical techniques. Hands-on exercises and thoroughly-explained solutions further reinforce student comprehension of chemical concepts and organic principles. An indispensable supplement to the primary text, this resource covers aromatic compounds, infrared (IR) and nuclear magnetic resonance (NMR) spectroscopy, nucleophilic and electrophilic aromatic substitution, ketones and aldehydes, carboxylic acid derivatives, and much more.
