Understanding chirality is important, not only to organic chemistry, but to understand the world around you in general. I like to think of chirality as ‘handedness’.
We have a right and left hand that are similar to each other, mirror images in fact. Yet our hands are not superimposable. A right glove will not fit a left hand due to the opposite ‘handedness’.
As you work through this series, pause and try each question and make sure you’ve mastered a topic before moving on.
Let’s start at the very beginning. WHAT is chirality? What does it mean for molecules? How can you identify a chiral carbon and what does that mean for its non-superimposable mirror image? All of this and more in video 1
Now that you understand about chirality, how do you find it’s absolute configuration to see if it’s R or S? Learn how to rank substituents using the Cahn-Ingold-Prelog system and using priorities to differentiate between R and S stereoisomers. This and more in video 2
Finding R and S is easiest when priority group #4 is towards the back. But how do you find if a molecule is R or S when group #4 is facing forward? More importantly WITHOTU having to visualize a confusing 3-dimensional molecule? Learn how to use my ‘think backwards method’ and how I learned this in the military by watching video 3 (coming late october)
Swap Method Trick for quickly finding R and S configurations when group #4 not forward/back. Save time AND forget your model kit and mental molecule manipulations redrawing structures on your exam.
This video shows you how to quickly and easily find R and S configurations directly on the Fischer Projection. Guaranteed to save you time on your next stereochemistry quiz/exam.
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.
