In the past four weeks, our time in lecture has been spent bridging the gap between principles (general chemistry) and preparing for the first exam. One topic that has a recurring theme between the two is hybridization. I have noticed two major groups of students: (1) those who need review, and (2) those who are … Continue reading The How-Tos of Hybridization
Molecular orbital theory (MO theory) can be a very challenging topic. Students come into the classroom already knowing about the octet rule, Hund’s rule, and the Pauli exclusion principle. However, the lecture component is critical for bridging the gap between their knowledge of general chemistry and organic chemistry. As such, I start my lecture on … Continue reading MO Theory and Its Relation to Molecular Stability
In today’s class, I spoke about the value of retrosynthesis, which allows chemists to view mechanisms and organic reactions from their products to their starting material. Typically, students are not keen on retrosynthesis because: 1). the word is scary, and students are introduced to many other difficult-sounding concepts while learning it, and 2). the process … Continue reading Forward vs. Backward: How Do You Get Students Interested in Retrosynthesis?
Chapter 11 of the Karty text focuses on electrophilic addition along pi bonds. This can be a tough topic to tackle. The terms themselves can scare students, which is why I've found that it is key to break down the words into smaller chunks, especially for elementary steps. In the text, a variety of electrophilic … Continue reading The Teeter-Totter Method: Helping Students Visualize Electrophiles and Nucleophiles
As an organic chemistry professor, I find that Fischer projections are one of the more challenging perspectives to view chiral centers. However, this projection also happens to be one of my favorites for viewing chiral carbons, chiral compounds, and meso molecules. Even though the Fischer projection can be quite challenging, it can also be the … Continue reading If H Is on the Horizontal…Then It’s Horribly Wrong
Students are notorious for feeling overwhelmed by the subject of organic chemistry. This leaves the instructor perplexed with the thought of effectively and adequately teaching the course. Often, the question posed is … "…to use or not to use reactions?" Both as a student and as an instructor, I have heard that students only feel … Continue reading Ballroom Dancing as a Metaphor for Learning Organic Chemistry
