Molecular Orbital Diagram For A Simple Pi Bond – Bonding And Antibonding
In the previous post in this series, “On Conjugation and Resonance“, I warned that in order to gain a deeper understanding of some of the

Molecular Orbitals of The Allyl Cation, Allyl Radical, and Allyl Anion
In the last post, we showed how to build a molecular orbital (MO) diagram for a typical C-C pi bond. We saw that: The number of molecular

In the last post in this series we built up the pi molecular orbitals of the allyl pi-system, consisting of three consecutive p orbitals in conjugation.
Read moreThe Pi Molecular Orbitals of Benzene
Today, let’s go through how to draw out the molecular orbitals of benzene. We’ll compare them with the molecular orbitals for (linear) hexatriene. The big takeaway

Today we’re going to go into the mechanism of the Diels-Alder reaction from a molecular orbital perspective. 1. A Quick Recap Of The Diels-Alder Let’s
Read moreThe Pi Molecular Orbitals of Cyclobutadiene
Previously, we’ve seen what the molecular orbitals of benzene look like, and that the fact that they are partially duplexed (or to use the proper nomenclature,

In our last post we showed that molecules with C-C pi (π) bonds absorb light in the UV-visible region, which promotes electrons from (bonding) π orbitals to

[Advanced] Secondary Orbital Interactions – A Rationale For Why Endo Products Are Favored In The Diels-Alder Reaction In our last post, we noted that endo products tend to be

If you come across just a few free-radical reactions, you should notice a familiar pattern. Every free-radical reaction that you’ll encounter is accompanied by either
