We’re going back to the lab! So far we’ve learned some important lab techniques that organic chemists might use day to day, like chromatography and proton NMR, but there are even more to learn. In this episode of Crash Course Organic...

In the previous episode we discussed what happens when we use electrophilic aromatic substitution to add a group to a benzene ring, but what happens when you try to add even more groups? Well, things get a little more complicated. In...

We’ve already learned a lot about electrophilic aromatic substitution (EAS) and benzene, but guess what? There’s even more to learn! In this episode of Crash Course Organic Chemistry we’ll revisit our old friends the Friedel-Crafts...

We’ve talked about benzene a bit already in this series, but did you know that benzene rings are present in all kinds of familiar substances? The styrofoam packaging that comes with new appliances, some pharmaceuticals, pesticides, and...

You gotta know your EAS reactions for this one! Make sure you do them in the right order, too.

We know about the products of these reactions, but how fast do they go? Give these a shot.

We are starting with benzene, we do four reactions, and what do we get? See if you can get the right answer!

EAS, not once, not twice, but thrice! Draw all the molecules, please. Don't forget about ortho/meta/para!

We've got a target molecule to synthesize, and we have to start from benzene and other reagents of three carbons or less. How are we gonna do this? Think about the reactions you know, especially some electrophilic aromatic substitution,...

Need some organic chemistry practice? Here's a tricky synthesis to try!

It explains various methods for preparation of alcohols and phenols and the chemical properties and reactions of alcohols and phenols.

An introduction to Friedel-Crafts chemistry.

Introducing electrophilic aromatic substitution.

A discussion of ortho/para directing and meta directing behavior amongst substituted benzenes.
