In the last post, we saw that ring strain of cyclopropane and cyclobutane were 27 and 26 kcal/mol respectively. They are the unhappiest of rings – constrained into uncomfortable angles, with hydrogens forced by geometry to grumpily line up side-by-side...
My friend Harry has an annoying habit. When we’re hanging out, every once in awhile, he’ll put on a serious face and say he has something very important to tell me. Then, when he has my attention, he breaks out thatannoying Bryan Adams song that...
In the last post we saw that cyclopropane and cyclobutane have an unusually high ring strain of 27 kcal/mol and 26 kcal/mol respectively. We determined this by comparing heats of combustion from rings of various sizes, and saw that the Hcombustion per CH2 was...

Zed Shaw teaches a course in writing Python called “Python the Hard Way“. Because the hard way is easier, he says.In the end, he’s right. If you really want to learn organic chemistry, the hard way is easier. In graduate school I had to un-learn...
Last time we talked about how some interesting electronic effects can lead to unexpected results in organic chemistry. Today we look at three examples of how steric factors can lead to unexpected products (or lack of products). The last example is a case where...
Over at Med School Odyssey, the author recently wrote about finishing Org 1, and has a lot to share about his experiences with the course. Here are some choice excerpts from that post, and from a few of his earlier posts.1. Don’t believe the hypeDont...

This is a loose transcript of the Syllabus Day speech I gave my Organic Chemistry I class on the first day of fall semester this week. Organic Chemistry I is the first of a two semester sequence at my small, Midwest, liberal arts university. Our five organic...
Well... this oughta cover it.I was reading comments to my reddit submission of the many oxidation states of carbon, and Aa1979 asked if the functional groups could be arranged logically according to actual chemical transformations. I replied that would be too...
