The Mechanism Did It!

I finally finished the book last night. In the two years since we adopted Karty, I have taught the first-semester course three times. However, due to the oddities of academic scheduling, this spring was my first time teaching our second-semester course with the text. So, metaphorically speaking, I finally got my chance to find out

My Surprising Favorite Second-Semester Chapter

My favorite chapter of second-semester organic chemistry is perhaps more surprising to me than anyone else, considering all the great mechanisms and reactions that fill the second-half of Karty’s textbook. My enjoyment of Chapter 16 (“Structure Determination 2: Nuclear Magnetic Resonance Spectroscopy and Mass Spectrometry”) is most likely due to my own experiences analyzing complex

All Downhill After the Aldol

Ah yes, it is that time of year again; a seven week coast to the Organic Chemistry II finish line. All the elementary steps have been introduced and discussed multiple times and it feels like review from here. Most texts seem to end with reactions like Aldol condensation and Robinson Annulation. A functional group approach

Favorite First-Semester Chapter: Chapter 9

My favorite chapter to teach in first-semester organic chemistry has to be Chapter 9 (“Nucleophilic Substitution and Elimination Reactions 1”) from Karty’s text. The introductions of S­N2/E2 and SN1/E1 reactions begin in Chapters 7 and 8, respectively, but Chapter 9 puts these reactions to the test and suggests to the students that reactions do not

Building on their Knowledge: From Atoms to Multi-Step Synthesis to Curing Sick Puppies

Karty’s mechanistic approach to organic chemistry provides the content organization to facilitate student success. In a functional group approach students are more likely to apply an incorrect mechanism to solve a synthetic problem. This is because classification by functional group does not provide an organizational level that allows students to classify reactivity. Organization by functional

My Most Productive Start of the Semester Ever

The first time I taught out of Joel’s text, I had no idea where I was going to put the semester break. I enjoyed how well each chapter flowed into the next, but that left me wondering where to put a five-week break. I was used to a traditional ordering of subject which resulted in

It’s My Favorite Time of the Year! Chapters 6 and 7

It’s my favorite time of the year. Finally, we get to do chemistry in organic chemistry! Not to malign BDE, IMF, chair vs. boat conformations, etc., but I have always thought of the stuff leading up to this point—strains and conformers, the designation of stereochemistry and the terms and rules associated with their nomenclature—a bit

No More Fearing Alkenes and Alkynes

Since this is the second year I am using Joel’s text, I was sure that I would be comfortable with the syllabus and schedule I set. But I again became nervous as I approached Chapter 11, “Electrophilic Addition to Nonpolar Pi Bonds.” Years of slogging through additions to alkenes and alkynes, working example after example

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

Starting the Semester with My Biology Students in Mind

Like so many other organic courses, at my school approximately two-thirds of organic students are biology majors. Of these, most have some sort of pre-health professional aspiration. Because of this audience alongside my chemistry and biochemistry majors, I come to my organic classroom (as I know many of you do!) with two sets of course
