Fischer Projection R and S Stereochemistry Trick

Chirality/Stereochemistry Video Series: Video 6 Fischer projections provide a simple 2-dimensional representation for complex 3-dimensional structures. Which is great for drawing complex molecules, but not so much fun if asked to determine R and S configurations. Many books and professors will have you redraw the Fischer projection into a 3-dimensional sawhorse or skeletal structure. I […]

R and S configuration for Lengthy Complex Substituents

Chirality/Stereochemistry Video Series: Video 5 R and S configurations are found by ranking substituents on a chiral carbon. This is relatively straight-forward when substituents contain 1-3 atoms. This gets more confusing when the substituents are long, complex, and contain many of the same atoms. This orgo tutorial video shows you how to approach lengthy and […]

Newman Projection Stereochemistry R & S Trick

Chirality/Stereochemistry Video Series: Video 7 Finding R and S configurations for non-traditional molecules can be somewhat tricky. This video teaches you how to quickly find configurations of molecules presented in a Newman Projection. Learn how to view the molecule and quickly assign priority WITHOUT the need to redraw into a sawhorse projection. (Watch on YouTube: […]

R and S Configuration using Cahn Ingold Prelog Priority Rules

Chirality/Stereochemistry Video Series: Video 2 Chiral carbons are identified as having 4 unique substituents. Finding the Absolute Configuration – R and S comes as a result of ranking and order substituents, specifically by noting the configuration of the top 3 groups. This video shows you how to prioritize substituents to find R and S configurations […]

Introduction to Stereochemistry Enantiomers and Chiral Molecules

Chirality/Stereochemistry Video Series: Video 1 Chirality is an exciting but potentially tricky topic in organic chemistry. Why? because it’s tough to visualize 2-dimensional drawings as a 3-dimensional structure. But don’t be like the thousands of students struggling with this topic. My chirality series will take you through this topic step by step to ensure that […]

Fischer Projection Stereochemistry Finding R and S for Single and Multiple Chiral Centers

Finding chirality for a 2-dimensional Fischer projection can be tricky. But it doesn’t have to be. This video shows you how to prioritize and rank groups on a Fischer projection when you have one or more chiral center. This video also addresses chirality when group #4 (H) is not going down/into the page (click to […]

Organic Chemistry Model Kit and Why You Should NOT Rely On It

If your professor says you can use your organic chemistry model kit on exams, I say DON’T. Don’t rely on it that is. Organic chemistry is a 3-dimensional subject that you learn on 2-dimensional paper. I know this sounds confusing but as an orgo student you’ll learn many tricks to work through 3-D problems on […]
