When I talk to other faculty who are using the Karty book I find that we share a love of Chapter 7. In this chapter, the most common elementary steps are presented, those being proton transfer, biomolecular nucleophilic substitution, coordination, heterolysis, nucleophilic addition, nucleophile elimination, biomolecular elimination, electrophilic addition, electrophile elimination, and carbocation rearrangements. Every … Continue reading Consistency is Key
As an educator, part of my summer fun is thinking about ways to revitalize and improve my courses in the coming year. This summer, the arrival of the third edition of Joel Karty’s Organic Chemistry: Principles and Mechanisms is giving me a lot to get excited about. While I have always appreciated the mechanism-based approach to organic … Continue reading Looking Forward with the Third Edition
I love finishing the year with a short dive into the dedicated chapter on polymers at the end of my textbook. In my case, I get to spend about two class periods on the chapter before the semester ends. That’s certainly not enough to do justice to every topic in the chapter, but it’s enough … Continue reading Polymers—That’s a Wrap!
While teaching chapters 17-18, I have shown students the versatility of carbonyls and enolate chemistry. The discussion in Karty’s book is arranged well and does a nice job of spotlighting the chemistry unique to carbonyls, especially as it ranges from selective addition (direct or conjugate) to the use of enolates for alkylation and halogenation. In … Continue reading Are pKa’s Necessary to Succeed in the Classroom?
Williamson ether synthesis at the basic leave is rooted in the conditions of an SN2 reaction. However, students still struggle with the content. I have found myself trying to remind my class of the basics. I am quite fond of the Karty text, and have tried to compliment the book mechanics with some organically-flavored A … Continue reading A, B, C’s of Williamson Ether Synthesis
Oftentimes, when I talk with students, I compare the organic chemistry lecture series to a study-abroad experience: the first semester is when students learn the language, and the second semester is when they become immersed in the content. Within this dichotomy, I view nomenclature as a vocabulary-learning process (e.g., ketones, carboxylic acids, alcohols, and so … Continue reading Nomenclature: Can It Be Taught alongside Mechanisms and Synthesis?
For the professors reading this post, I am writing to gain some insight by asking for your advice. Even though I have been teaching organic chemistry for five years now, I still struggle with how to assess my students’ knowledge. When I was a student, we had a series of free-response/short-answer questions on our exams. I … Continue reading How Do You Keep Content Fresh for Students While Also Maintaining the Integrity of Your Course?
We have now approached Exam 3, which means that students have been exposed to material that includes Chapter 19 content. I am quite excited to see that my students are starting to build their “organic chemistry toolbox,” but I've also noticed that they are starting to confuse how and when reagents are used. While I … Continue reading Building Students’ Organic Chemistry Toolbox to Set Them Up for Exam Success
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?
When teaching mechanisms, I try to impress upon my students that the concepts tied to mechanisms are not confined to the chapters that they appear in within the Karty text, but rather, that they are a continuation of connected topics across the discipline as a whole. Today’s class focused on Sections 13.1-13.3, which elaborate on … Continue reading Everything Is Connected: Teaching Organic Chemistry as a Unified Story through Mechanisms
