Life is Hard Enough. Why Teach Alkenes By Function?

One thing I was really looking forward to when switching to Karty’s mechanistically organized text was how reactions involving alkenes would be addressed. I expected to see the reactions simply grouped by mechanism; for example, the electrophilic addition reaction mechanisms would be grouped together, as would the pericyclic reaction mechanisms and so on. Instead, I … Continue reading Life is Hard Enough. Why Teach Alkenes By Function?

Students are Doin’ it for Themselves

As several contributors to this blog have pointed out, Joel Karty’s text introduces biochemistry topics early in the course through supplementary sections at the end of most chapters titled, “The Organic Chemistry of Biomolecules.” Many instructors have lauded this early inclusion of biomolecular topics as a motivator for biology majors and pre-professional students; one that … Continue reading Students are Doin’ it for Themselves

A Racemization Revelation

In my experience, when students are writing a reaction mechanism, the most common error is to form a strong base under acidic conditions or vice versa.  I stress the importance of paying attention to reaction conditions in lecture, but the “function group” based textbook previously used at Western Washington University did not contain a section … Continue reading A Racemization Revelation

You Are Ready for the Final Once You Drink Some Coffee

We made it to the final chapter: Chapter 26 (“Polymers”). Each student is filled with a sense of pride that they have read every chapter in their textbook. Chapter 26 allows us to review mechanisms from throughout the text with real world applications. These applications are good preparation for next week’s final. In discussing them, … Continue reading You Are Ready for the Final Once You Drink Some Coffee

Happy Holidays!

Another semester of teaching the mechanism is over! Last year, Rick Bunt of Middlebury College wrote this festive end-of-the-semester song for his students (sung to the tune of “Rudolph the Red-Nosed Reindeer”). It's so good we thought we'd post it again! You’ve had Spanish and Bio And History and Calc, Physics and Econ And Poly Sci … Continue reading Happy Holidays!
