Fischer Indole Synthesis
We've talked about a few heterocycles, but one important aromatic one we didn't mention is the indole. This is a component of a variety of biomolecules. So how can we make them? Nobel prize winner Emil Fischer developed the Fischer...

How to Balance Chemical Equations
The video is a tutorial on how to balance chemical equations. The instructor goes through three different equations, counting the number of elements present on each side and then adjusting the coefficients to balance the equation. The...

NASA | Propylene on Titan
With a thick atmosphere, clouds, a rain cycle and giant lakes, Saturn's large moon Titan is a surprisingly Earthlike place. But unlike on Earth, Titan's surface is far too cold for liquid water - instead, Titan's clouds, rain, and lakes...

Introduction to Esters: Naming and Making Esters
The video explains what esters are, how they are made and named, and their uses in fragrances and flavorings. The process of making esters is demonstrated through the reaction between carboxylic acids and alcohols in the presence of a...

Oxidation of Alkenes Using Potassium Permanganate (Hot and Cold Conditions)
We've seen that KMnO4 can oxidize alcohols and aldehydes to give carboxylic acids and ketones, but this reagent can also oxidize alkenes. The product(s) will be different depending on whether we use cold basic conditions or hot acidic...

Introduction to Addition Polymerization
This video is a tutorial on addition polymerization, the process of joining monomers together to form polymers. It explains the use of functional groups and double bonds in alkenes to create single bonds in polymers. The video also...

Practice Problems: Labeling Carbons
What's with this hierarchy? Primary, secondary, tertiary... can't all carbons be equal? Well, no. We need to be able to label the degree of substitution of any carbon in an organic molecule so that we can make predictions about the...
