How Science Got Us to 2020 | Compilation
As we forge ahead into the new year, let’s take some time to thank the intrepid researchers, volunteers, and even the occasional dog who came before us, made sure our food and drugs are free from poison, and built the devices that make...

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...

Stereochemistry - Crash Course Organic Chemistry
The shape of molecules is super important to life as we know it. In this episode of Crash Course Organic Chemistry we’re learning about stereochemistry and how to identify molecules as chiral or achiral. And as always, we’ll be doing a...

Thalidomide: The Chemistry Mistake That Killed Thousands of Babies
On October 1, 1957, thalidomide was introduced as a new morning sickness cure. Everything seemed great until later the next year, when thousands of infants were born with severe birth defects.

Practice Problem: Types of Protons
We learned about how pairs of protons can have specific relationships. They can be homotopic, enantiotopic, diastereotopic, or heterotopic. Let's apply this to some examples!
Professor Dave Explains
Practice Problem: Newman Projections and Nomenclature
For this one, we will need to be able to draw Newman projections as well as name the molecule using the rules of IUPAC nomenclature. Basic stuff!

Stereochemistry: Enantiomers
Defining stereochemistry and enantiomeric relationships.
Khan Academy
Introduction to Chirality, Stereochemistry, Organic chemistry
An introduction to chirality and whether molecules can be superimposed or not. The terminology for those molecules is given along with the relevance of that characteristic.
