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?
Rarely are real-world applications of chemistry emphasized enough in the mainstream organic chemistry course. This can explain why students tend to view chemistry as structures on the page or as schemes drawn on the white board. A strictly two-dimensional discussion of chemistry can be one of the reasons that students struggle to connect what they … Continue reading Chemistry in the Real World: Applications That Bring Life to the Page
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
We have written a handful of blog posts that call attention to the benefits of Chapter 7, which introduces students to the 10 common elementary steps involving closed-shell species. Because of Chapter 7, students are exposed to the complete set of the elementary steps that make up the mechanisms for all reactions encountered through Chapter … Continue reading What’s Good for the Goose is Good for the Gander: Elementary Steps for Radicals
One of my favorite teaching moments throughout the entire year comes in Chapter 23, when, in the same lecture period, we examine aromatic substitution reactions proceeding through three different intermediates: arenium ion intermediates (first reaction below), Meisenheimer complexes (second reaction below), and benzyne intermediates (third reaction below). I love this as a teaching moment because … Continue reading A Great Teaching Moment with Aromatic Substitution Reactions
Here at Teach the Mechanism we are excited to introduce you to Dr. Christine Pruis, our full-time on-staff Chemistry Subject Matter Expert. In the following post, Dr. Pruis discusses her journey with authoring the Smartwork5 online homework and how this resource facilitates learning and understanding organic chemistry and mechanisms when paired with Joel’s text. Read … Continue reading Smartwork5: Immediate Formative Assessment Opportunities Help Students Work Smart
My entire academic career as both a student and as an instructor, I have always taught or been taught organic chemistry using the functional group approach: beginning with the tried and true method of labeling chapters by functional groups and then moving on to learn how to name, synthesize, and react with the functional group … Continue reading First Impressions: The Big Switch, Part 1
When I first heard Joel Karty speak about his mechanistic organization in his organic chemistry text around 2016, I had also heard a lot of buzz about flipping the classroom. I was very curious about trying this in my own classroom, but implementing self-directed learning with a more intricate discipline like organic chemistry can seem … Continue reading Flipping the Script: Mechanistic Organization Encourages Cooperative Learning
