Chirality/Stereochemistry Video Series: Video 4 R and S configurations are pretty straight-forward when priority group #4 is conveniently in the back of the molecule. There’s even a quick trick for when group #4 is forward (as taught in this video). But what happens when priority group #4 is in the plain of the page? Do […]
Chirality/Stereochemistry Video Series: Video 3 This video shows you why and how to reverse R and S when group #4 is forward to help you quickly and easily master relative configurations when studying chirality and stereochemistry. (Watch on YouTube: Group 4. Click cc on bottom right for video transcription.) <– Watch Previous Video: R and […]
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 […]
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 […]
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: […]
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 […]
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 […]
