you could also tell the difference between R and S by the direction of the arrow and connecting it to the way both letters R and S are written .
when writing R you have to go clockwise (the upper part of it)
and when writing S you have to go counter clockwise .
good tip
THANK YOU SO MUCH. My professor taught us how to get the R and S for the simplest molecule, then gave us an extremely complicated one for the exam.. I learned more from you in 15 minutes than I did in 2 hours with my prof.
You're very welcome, so happy to help!
My professor makes this look so hard. So the problem is not the topic but the way some professors teach it.
Sometimes we need a different take to understand.
future pharmacist here. thank you so much!

mahadi hasan this was all pretty straightforward...consult a dictionary if you still don't get it :)
Lol same here
hi quick check were you able to become a pharmacist?

Thank you! I was confused for about an hour, but after seeing your video, I get it now.
Awesome! Glad it helped!
thank you, most simplest and most concise terms of any of the videos i've seen on this topic
You're so welcome!
Madamme LEAH! You are so much good in Organic Chemistry, You make Hard things in Stereochemistry simple as much a possible, I appreciate You and U always be blessed! Continue by doing so for other courses to help Us enjoy Chemistry or become better Chemists!
Wow, thank you! Happy to help!
Outstanding explanation of difficult topic!
Amazing work
This channel must have millions of subscribers!

Thank you so much, Ms. Leah; I appreciate you.

I know this was so long ago, but still. thanks Leah.
FYI you can always think of it as a steering wheel, pull down to the right to turn right -R
and the old term for left-handed was sinister.
pull down on the left to turn left -S
You're welcome! Great tip for memorization. :)

AT 11:53 does it matter where you place the hydrogen atom? For instance would there be any difference if you draw to the left of OH? Thanks
Technically the dashes going back should be directly behind the OH group, but then you wouldn't be able to see it. As such it's customary to draw it offset to either side, right or left, to show that it's going away and into the page
you are an idol mam.. loved ur vedios
Glad you've enjoyed them :)
Thanks
You're welcome!
thanks a lot, this was very helpful lecture. i think my professor prepared from your video but did not convey that good. ;-) , once again thanks.
You're very welcome! I'm glad to hear my video made it clearer for you.
THANK YOU SOOOO MUCH！！ you are my god❤
You're very welcome, but just a person, not a god. I don't want to be in control of that much! ;)
This made so much sense. Excellent oratory skills and superb explanations. This was wayyy better than 2 weeks of professor's explanation. Cheers Leah, you're a lifesaver!
