The Diels-Alder & Other Pericyclic Reactions: Crash Course Organic Chemistry
Going out in the sun can work wonders for your mood, but unfortunately too much UV exposure can do serious damage to your DNA. This damage occurs through a type of organic reaction called a pericyclic reaction. In this episode of Crash...

Solid State Electrical Properties and Band Theory
Electrical conductivity varies from metals to insulators. Solids can be divided into three categories: conductors, insulators, and semiconductors. Conductors are solids through which electricity can flow to a large extent, classified as...

Examples of s-p Mixing in Molecular Orbital Theory
Admittedly, my prior tutorial on MO theory was a little confusing, and had some errors. I wanted to make things right, so here's another one! This will clarify some of the basic concepts, and will also extend them to discuss a new...

More Complex Ligands in Organometallic Chemistry
We've covered the basics regarding ligands that can be found in transition metal complexes. But it gets quite a bit trickier than that. What about polyhapto ligands? Bridging ligands? Polydentate ligands? What could all of this mean?...
Professor Dave Explains
Metallic Bonds
We've learned about ionic and covalent bonds, so we understand the interactions that will occur between a metal and a nonmetal, or between two nonmetals. But what about two metals? Metallic bonding! This ends up being sort of like ionic...

Pericyclic Reactions Part 1: Revisiting the Diels-Alder Reaction
An important class of reactions is the pericyclic reactions. We've been introduced to one subclass of these, cycloaddition reactions, when we looked at the Diels-Alder reaction. For the next few tutorials we will learn about some other...

Valence Bond Theory, Hybrid Orbitals, and Molecular Orbital Theory
Alright, let's be real. Nobody understands molecular orbitals when they first take chemistry. You just pretend you do, and then in your next course you learn them a little better. And then a little better than that. And five years later...

Conductivity and Semiconductors
Why do some substances conduct electricity, while others do not? And what is a semiconductor? If we aim to learn about engineering and technology, this will be a very important concept, so let's go through the basics now!
