Organic Chemistry: Principles and Mechanisms 2nd Edition Pdf Book Description:

Focused on the Student, Organized by Mechanism When an organic reaction is presented to a novice, only the structural differences between the reactants and products are immediately apparent. Students tend to see only what happens, such as the transformation of one functional group into another, changes in connectivity, and aspects of stereo chemistry. It should therefore not be surprising that students, when presented reactions, are tempted to commit the reactions to memory. But there are far too many reactions and accompanying details for memorization to work in organic chemistry.

This is where mechanisms come into play. Mechanisms allow us to understand the sequences of elementary steps— the step-by-step pathways— that convert the reactants to products, so we can see how and why reactions take place as they do. Moreover, the mechanisms that describe the large number of reactions in the course are constructed from just a handful of elementary steps, so mechanisms allow us to see similarities among reactions that are not otherwise apparent. In other words, mechanisms actually simplify organic chemistry. Thus, teaching students mechanisms— enabling students to understand and simplify organic chemistry— is an enormous key to success in the course. At the outset of my teaching career, I fully appreciated the importance of mechanisms, so during my first couple years of teaching, I emphasized mechanisms very heavily. I did so under a functional group organization where reactions are pulled together according to the functional groups that react. That is the organization under which I learned organic chemistry, and it is also the way that most organic chemistry textbooks are organized. Despite my best efforts, the majority of my students struggled with even the basics of mechanisms and, consequently, turned to flash cards as their primary study tool. They tried to memorize their way through the course, which made matters worse.
