Crossed Aldol Reactions, Enones, and Conjugate Addition: Crash Course Organic Chemistry
Insects can communicate with each other about all kinds of things, but instead of using words, they use… you guessed it! Organic Chemistry! Insects can send signals to each other by secreting compounds, and one such compound used by...

Intro to Substitution Reactions - Crash Course Organic Chemistry
Substitution reactions can have really powerful effects, both good and bad, in our bodies. You might remember substitution reactions as displacement reactions from general chemistry, but (you guessed it!) in organic chemistry they’re a...

Determining SN1, SN2, E1, and E2 Reactions: Crash Course Organic Chemistry
Organic chemistry isn’t that different from an adventure game, with substrates as characters, nucleophiles as magic potions, and reaction conditions as different magical kingdoms. In this episode of Crash Course Organic Chemistry, we’ll...

Diazonium Salts & Nucleophilic Aromatic Substitution: Crash Course Organic Chemistry
Have you ever wondered where cured meats like salami or pepperoni get their bright red color? Of course its from organic chemistry! A chemical called nitric acid gives them that bright color, while also increasing their shelf. It's also...

An Overview of Aldehydes and Ketones: Crash Course Organic Chemistry
Ketones and aldehydes are all around and inside us, from the strong smelling component of nail polish remover, acetone, to hormones in our bodies, to drug treatments for allergies, COVID-19, and even cancer! We’ve already learned a bit...

Nucleophiles: The Atom Seekers of Organic Chemistry
Nucleophiles, often referred to as "nucleus lovers," are chemical species that donate an electron pair to form a bond. They attack positively charged or electron-deficient atoms in a molecule, making them key agents in substitution and...

Practice Problem: Mechanism - Reaction of an Epoxide
For this one we will have to know what epoxides do! It's a pretty neat little mechanism.
Professor Dave Explains
Practice Problem: Reaction of a Terminal Alkyne
We've got a terminal alkyne, and we're gonna do some stuff to it. What will we get? What's that Grignard reagent gonna do? Be careful!
Professor Dave Explains
Practice Problem: Grignard Reactions
Grignards are all over the place! Better make sure we can draw the correct products of Grignard reactions. Try these for practice.
Professor Dave Explains
Practice Problem: Crossed Aldol Products
Enolate chemistry is tricky business! You might get more products than you think. Give this one a shot.
Professor Dave Explains
Practice Problem: Drawing Substitution and Elimination Products (SN1/SN2/E1/E2)
I know you guys are dying for more practice choosing between SN1/SN2/E1/E2 mechanisms, so hopefully this one helps a little. Make sure to look at all the factors we talked about in my tutorial on this topic!

Nef Reaction (Introduction to Umpolung Chemistry)
The Nef reaction is a good way to convert nitronates into carbonyl compounds. This is a technique that can be incorporated into a strategy called "Umpolung", which refers to a reversal of polarity, such that upon converting from the...
