Organic chemistry: R and S naming (3)

Organic chemistry nomenclature: How to determine whether a stereocenter has R or S stereochemistry--i.e., how to name the "absolute configuration" of a stereocenter.

These videos are designed to help students who are finding the material difficult, so I go very slowly, with lots of repetition and examples. If you don't find this material difficult, you might be very bored by these videos and might prefer to learn straight from a textbook.

Im amazed at technology of internet to deliver amazing resources like this. Brilliant stuff

Great technique for naming compounds containing Chirality Centers. Excellent video.

i love you

[andycasdmx]

how dare he say triple H has the lowest priority.

You are a great teacher! Because you worked so systematically and explained it so well, I totally understand it now! Thank you very much!

[badwan92]

i did this in 10 seconds why is he taking so much time ?? thanks alot though !!

@gangsta0524 It is S. Counter-clockwise means S and clock-wise is R. UNLESS the lowest one happens to be a wedge or if you do a SN2 reaction on that stereo center then it changes to the other(so R to S and vice versa)

[gangsta0524]

so is it R or S

You might have just saved me from failing my exam! Thank you so much!
