A number of years ago I had a student come to me at the end of Organic II and ask, “What happened to the SN2 reaction?” She wanted to know why we had spent so much time on this one reaction in order to move on to the next unit and then never discussed this … Continue reading The Organization Makes Mechanisms Part of the Routine
Reasoning By Analogy
For twelve years I’ve taught organic chemistry to a mixture of chemistry and biology students. I always begin Organic I by asking my students this same question: Why are you taking this class? Some students respond that the curriculum plan for their major or career requires the organic chemistry course sequence. For other students, organic … Continue reading Reasoning By Analogy
The Benefits of a Mechanistically Organized Book When Teaching a 2-cycle Approach
Two-cycle organic chemistry is a pedagogical approach that has gained in popularity over the last couple decades. It’s a rather simple idea: The first semester course is treated as something of a survey, dealing primarily with the fundamentals, whereas the second semester revisits many of the same topics from the first semester, but treating them … Continue reading The Benefits of a Mechanistically Organized Book When Teaching a 2-cycle Approach
The Chapter Every Organic Textbook Should Have
This unique chapter is the game changer for how students perceive organic reactions. Whenever I discuss Joel’s textbook with colleagues, this chapter is the first aspect of the book that I mention. Chapter 7, “An Overview of the Most Common Elementary Steps,” briefly surveys ten steps: Proton transfer SN2 Bond formation (coordination) Bond breaking (heterolysis) … Continue reading The Chapter Every Organic Textbook Should Have
Liberation in the Laboratory
One of the unexpected benefits of Joel’s organization was the discovery that students, once they learn the elementary steps common in organic reactions, can perform a limitless—at least in theory—range of experiments in the lab. (In the upcoming textbook, elementary steps are discussed in Chapter 7, midway through the first semester.) Since students have examined … Continue reading Liberation in the Laboratory
