Antibonding Molecular Orbital: Definition & Overview

1. Antibonding Molecular Orbital: Definition & Overview

In this lesson, we will be learning about what an anti-bonding orbital is in terms of molecular orbital theory and getting a brief overview of its role in molecular systems.

Butadiene: Uses, Polymerization & Production

2. Butadiene: Uses, Polymerization & Production

The main focal point of this lesson will be on an organic compound known as butadiene. Our primary points of discussion will include how it's made, the polymerization reactions it takes place in, and its most important industrial uses.

Cycloaddition Reactions in Organic Chemistry

3. Cycloaddition Reactions in Organic Chemistry

The focal point of this lesson will center around a specific type of reaction in organic chemistry known as a cycloaddition reaction. Our lesson will include a brief survey of some of the more important cycloaddition reactions encountered.

Diels-Alder Reaction: Mechanism & Stereochemistry

4. Diels-Alder Reaction: Mechanism & Stereochemistry

In this lesson we will learn the mechanism by which the Diels-Alder reaction creates a new six-membered ring. We will learn what reactants are necessary, and how the stereochemistry of the products turns out based on the reactants.

Intramolecular Diels-Alder Cycloaddition Reactions

5. Intramolecular Diels-Alder Cycloaddition Reactions

The Diels-Alder reaction forms a new cyclohexagon. When the diene and dienophile are on the same molecule, an intramolecular reaction occurs. We will learn under what conditions this reaction can occur and look at some examples.

Retro-Diels-Alder Reaction: Mechanism & Overview

6. Retro-Diels-Alder Reaction: Mechanism & Overview

In this lesson we will learn about the Retro-Diels-Alder reaction and how it works as the reverse of the Diels-Alder reaction. We will learn how to determine what products are formed and the stereochemistry of those products.

Drawing Products of Diels-Alder Reactions: Practice Problems

7. Drawing Products of Diels-Alder Reactions: Practice Problems

In this lesson we'll be practicing determining the products of Diels-Alder reactions. We'll learn how to identify different components of the reactions, push electrons to form new bonds and draw the products with correct stereochemistry.

Bredt's Rule in Organic Chemistry

8. Bredt's Rule in Organic Chemistry

Bredt's rule came about due to an observation of bridged-cyclic molecules. In this lesson we will learn what Bredt's rule is, why it occurs, and discuss some applications.
