Professor Dave explains the science and theory behind pericyclic reactions (Part Two)
Professor Dave Explains
Heterocycles Part 1: Furan, Thiophene, and Pyrrole
We've mentioned heterocycles before. They are cyclic molecules where one or more atoms in the ring are not carbon. Typically these involve oxygen, nitrogen, and sulfur. But there are so many different heterocycles. Different sizes, some...

The Haloform Reaction
Once again, we will be interested in learning about reactions that break carbon-carbon bonds, as this will allow us to perform necessary transformations on substrates. The haloform reaction is one such reaction, and it is commonly used...

Carbenes Part 2: Cyclopropanation, C-H Insertion, and the Bamford-Stevens Reaction
In the previous tutorial we learned about carbenes. So now that we understand their properties, we are ready to learn about what we can do with them. Three major uses of carbenes involve cyclopropanation, C-H insertion, and the...

Beckmann Rearrangement
Have you ever had a ketone and wished you had an amide instead? Not to worry! The Beckmann rearrangement is the solution to your problems. Check out this nifty reaction where we get an oxime and then get an alkyl group to migrate. We can...
Professor Dave Explains
Diazomethane Synthesis and Applications (Arndt-Eistert Homologation)
In learning about carbenes, we discovered the importance of diazomethane. So it will be a good idea to learn how to make this molecule, as well as some other things we can do with it, including something called the Arndt-Eistert...
Professor Dave Explains
Baeyer-Villiger Oxidation
We just learned how to make lactams out of cyclic ketones, is there a similar way that we can make lactones? There is! Try the Baeyer-Villiger oxidation. This is another one of those rearrangement type of reactions, only this time we are...

CHEMISTRY - Matter - Structure and Bonding of Elements & Compounds (part 1)
NOTE: animation error at 2:40 - the periodic table is supposed to be twisted clockwise, and not like it is shown in the video. The twisting enables the element Cs to appear on the extreme left and the element F to appear on the right. In...
Professor Dave Explains
Heterocycles Part 2: Pyridine
In the previous tutorial, we learned about some five-membered aromatic heterocycles. Those were furan, thiophene, and pyrrole. Now let's learn about a six-membered one, pyridine. This one is ubiquitous in nature, so let's get the scoop...

Assigning R/S on Fischer Projections
We've learned about stereochemistry and also how to assign absolute configuration (R/S) to stereocenters using the Cahn-Ingold-Prelog convention. But some students are forced to learn all of this on dreaded Fischer projections. These are...

Stereospecificity vs. Stereoselectivity and Regiospecificity vs. Regioselectivity
Many organic chemistry students think that specificity and selectivity are essentially synonymous when describing the potential products of a chemical reaction. But this is not true! They have separate meanings and imply different...
