An incredibly good explanation of a complex topic! Even professors can benefit from your videos - namely, from the way you present the subject! Thanks!
Thanks a lot Mam..i am preparing for IIT-JEE exam in India and was facing some problems in stereochemistry ..But your video cleared all the doubts from my mind ..Once again, thanks a lot..
In the Cahn-Ingold-Prelog priority system, we branch out from the chiral carbon one atom at a time and consider the direct points of contact of each 'branch'. The Carbon of C(CH3)3 is directly bonded to three other carbon atoms, while the Carbon that takes number 2 is directly bonded to only one other carbon and two hydrogens. In other words, the sulfur is just one spot too far away, or one spot removed from changing the order of the priority.
I can tell you that this compound is not a cis compound, as the two substituents are drawn on opposite faces of the ring. That makes it a trans configuration. As for your other question, this is not exactly what this video was made to cover. Since I don't offer tutoring over social media, for help with questions like this and more, I recommend joining the organic chemistry study hall.

If you hit the same group you don't stop, instead you check what's next. I cover this in this video: leah4sci.com/r-and-s-configuration-for-lengthy-complex-substituents-2/
I'm sorry for that and thanks for letting me know. This is the recording of a live workshop and I was assured sound was ok, also sounds fine on my end so I wonder if perhaps it's your device? try it on another device and let me know if that's any better

Oh wow, thanks so much!
Thank you. You are a lifesaver. Thank you for specifically 11:00, I've just not ever done a ring and was just totally lost.
So glad it helped, especially with rings which are often tested
This helps me a lot to prepare my exam! Thank you for your hard work❤️
You're welcome 😊
You are the BEST!!! So clear and easy to follow, thank you!!
You are so welcome!
you saved me from this eternal headache, ty
You're very welcome!
this video is literally a lifesaver
So glad to help!
You have explained very well. The examples are amazing.
Thank you!

You're very welcome! Best wishes on your exam!
Thanks madam for your effort to make me understood everything in less than 5minutes❤🎉🎉
You're very welcome! I'm glad this video was useful for you. :)
At 12:12 , why did C(CH3)3 take number 1 ? Its (C_C_C but the other one is C_C_S ) and S has a priority ?! 😢

Please make English subtitles your videos. This makes learning easier for non-English speaking countries
I'm confused. This video (almost all of my videos) has English captions. Be sure to turn them on in the lower right corner of the video player
真的非常感謝你!!!題目我也都做對了，現在覺得立體化學真有趣XD THANK YOU!!!
you're welcome
Thank you so much mam! Really very helpful😊
You're so welcome. Glad to hear it!
Thanks Mam, your entire series is really helpful 😀
You're very welcome. Glad to help
i have a question is this a cis compound also ? 12:32
so how many sterioisomers it has ? is it 8

great. checked your work for our free mcat course. thanks
Glad to hear that! Feel free to refer your students to my channel. :)
How do you find or locate the invisible hydrogen
Look for my drawing skeletal structures video because I go into that concept in detail
Thank you ma'am to clear my concept .
you're so welcome
thank you for all your hard work ❤️
You're very welcome!
I came up with my own Pneumonic to remember the order of those atoms -- Can OF PepSi Cola (for CNOFPSCl)
Use what works for you!
thanks so much for this pneumonic!
Thanks Leah love you
Yo're very welcome!

The wedges are coming towards you to say hi, the dashes are dashing away bc they’re shy.
Yes, I like it!
Super teaching mam
Keep doing videos like this mam
Thanks so much!
for the last problem, why carbon bond to SH, H, CH2 and CH2 on the ring is chiral ?? it doesnt have 4 different group
If you hit the same group you don't stop, instead you check what's next. I cover this in this video: leah4sci.com/r-and-s-configuration-for-lengthy-complex-substituents-2/
Doesn't the 4th priority have to be on a dash???
Yes, but that's where tricks come in
I'm sorry. I'm come from VietNam.I'm not good at English. Can you translate the word ' swap'?. Thank you
I don't know, but www.deepl.com/translator is a good one to use. Thanks for watching!
Thank you
You're welcome
thanx, 😭😭❤❤❤
You're very welcome
Mam, in which college did you study

Interesting.
how so?
Sound quality is not good, and echoing. Would you please record the sound in better quality. Thanks
I'm sorry for that and thanks for letting me know. This is the recording of a live workshop and I was assured sound was ok, also sounds fine on my end so I wonder if perhaps it's your device? try it on another device and let me know if that's any better
🥰
:)
i am falling in love❤
Let's keep it professional, lol. Seriously though, happy to help.
