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...

This video explains the concept of chemical reactions and provides clues to recognize when they occur. It highlights examples such as color changes, bubbling, heat or light production. This video is part of the 7-part series, Chemical...

In this video I discuss "What is chemical engineering?" To put simply, in chemical engineering you design processes to transport, transform, and produce materials. Chemical engineering is much more than just working with chemicals. You...

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...

Professor Dave explains the science and theory behind pericyclic reactions (Part Four)

In this video, we’re going to learn about the loss of mass in a chemical reaction, how it happens and why we measure this. The total MASS of reactants will be the same as that of the products, as mass is always conserved in a chemical...

This video is a review of the topics covered in the Chemical Changes series. In this series, we learn that matter is composed of different elements and can undergo chemical changes, transforming into new substances. We also compare...

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...

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...

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...

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...

Professor Dave explains the science and theory behind pericyclic reactions (Part Three)

In this video, we’re going to learn about the loss of mass in a chemical reaction, how it happens and why we measure this. The total MASS of reactants will be the same as that of the products, as mass is always conserved in a chemical...

In this video I discuss "What is civil engineering?" Most people probably know this major consists of working on bridges, buildings, dams, and so on. But you may not know that civil engineering is broken up into different subfields that...

Now that we've covered some basics regarding drug nomenclature, drug administration, and the ways they move through and interact with the body, it's time to dive into a survey of specific drugs so we can learn about as many as we can....

Upon viewing the Investigating Chemical Reactions video series, students will be able to do the following: Define a chemical reaction as a process in which substances undergo changes to produce new materials with different properties....

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...

Upon viewing the Investigating Chemical Reactions video series, students will be able to do the following: Define a chemical reaction as a process in which substances undergo changes to produce new materials with different...

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...

This video explains how heat, pressure and chemical reactions may transform one type of rock into another. The formation and classification of metamorphic and igneous rocks is highlighted. Other terminology includes: extrusive rock,...

Neuroscience has enabled us to explain how the brain affects the body. Yet there is no theory to explain how the matter of the brain creates thought and experience. Is consciousness inexplicable because it is not part of the material...

In this video, the teacher explains why zombies are impossible by examining the stages of death and the decomposition process in the human body. They discuss the effects of rigor mortis, lack of oxygen to the brain, and the breakdown of...

The video explains how chemical reactions can be used to produce electricity, starting with cells and batteries. It describes how a simple cell is made by connecting two different metals with an electrolyte and explains how the potential...

This video is a lecture presentation about digestive enzymes and how our bodies process the food we eat to extract important nutrients from it. The presenter explains the two types of digestion - mechanical and chemical, and focuses on...
