The Right Time for Synthesis?

At Butler, we have four learning goals for our students in organic chemistry: to learn the language, drawing style, and three-dimensional structure of organic molecules; to know and apply organic reactions; to demonstrate understanding of reaction mechanisms; and to integrate this knowledge through synthesis. Of these learning objectives, the most difficult for students to embrace

Mechanisms in Class, Mechanisms in Lab

I have always used a mechanistic approach when teaching organic chemistry. Every class I have taught, I started the first day saying, “Do you want to try to memorize hundreds, if not thousands, of individual reactions, or do you want to learn to understand how about ten reactions take place, so you can apply them

Teaching Solvent Effects Early Helps Keep Students’ Heads From Spinning

We started Chapter 9 in class a couple weeks ago, where we learn how to predict the outcome of the SN1/SN2/E1/E2 competition. Similar to how it’s done in most books, we do this by first learning about the major factors that influence the rate of each reaction in this competition. But unlike other books, this
