thank you! My brain hurts from trying to assume so many rules with no prior knowledge. You make the rules seem so simple I can finally get through my hw like a checklist.
This video is truly incredible. I’ve never struggled in figuring out the configuration until the hydrogen was in the front. You’ve explained it so well, it is the easiest thing ever!! I wish more people knew about this life hack.
Hi, thank you so much for such a valuable video. The explanations are clear and understandable to me. R and S configuration isn't sinister-looking for me anymore)
Thank you very much for this video. Could you please make a video about how to study organic chemistry and what are the easier and more informative resources for it ? (Especially for pharmacy students)
That's a great suggestion! My best advice would be to do lots of practice problems, using your textbook or old exams if your prof gives you access to them. And study with friends because it will give you different perspectives on how to approach the problems :)
sorry why for problem 2 do you have the second priority carbon in the ring connected to OO and C. I know its a double bond but I figured you'd just count 2 O's but you also count an extra C? Is this always the case? thank you for your advice!!
Why is the bromid on the right an the CH3 on the left in the first example of the practice ? Would have drawn the bromid on the left as in the drawing and the CH3 to the right and therefore I got a R configuration. :/
Hi, I have a question! In the "double swap" exercise the initial configuration of the molecule is S (Cl -> F -> et) but at the end, when we put the Hydrogen to the back we have the R configuration. Why do we obtain the opposite configuration even if we did 2 swaps? I can't really get it 😢
Through Fischer project can every rs problems be possibley solved? I solve actually transfering the compound to Fischer but i don't know,is every rs problems possible or not through Fischer..
One question In the aminoacid cysteine we have 4 different Atoms attached to the stereogenic carbon 1. N (NH3) 2. C(A) (CH2 - SH) 3. C(B) (COOH) 4. H Apparently at first glance we see that N > C(A) = C(B) > H. So we have for sure that nitrogen is in first priority while hydrogen is in fourth Secondly we are gonna compare Carbons A and B and we see that Carbon A is attached to 2 hydrogens and one sulfur (a.n = 18) On the other hand we see that Carbon B has one double bond and one single bond with oxygen. You write that to assign a priority to an atom that is part of multiple bond, treat a multiply bonded atom as an equivalent number of signly bonded atoms. CO2 ---> CO3 But if we do that in the Carbon B we will have a greater atomic number than 18. Therefore the configuration of cysteine will be S and not R. What am i doing wrong then??
Best video on r and s configuration I have found on youtube so far 👏

This was explained so so well❤
Thank you so much for this great video! It is really helpful!
Thank you so much for making these videos. They are so helpful!
You’re welcome!
RUclips recommended me your video and now I am totally sure this is going to save my next Organic Chemistry exam. Thank you sm!!
Best explanation I have found so far. Was really struggling with putting the lowest priority group in the back, now it seems easy!
Thank you very much,I have no a word to express your knowledge
You are so amazing at teaching these concepts. Thank you so much for your hard work and time you put into these videos. Thank you again!

Amazing video, thank you so much! It simplifies the topic and explains it clearly
thank u best video i’ve come across
You are legit amazing❤...finding your channel has made my day🌱
BEST VIDEO IN RUclips!!!
Very useful and clear! Thanks for sharing!
Thanks a lot ! New subscriber right here.
Thank you so much for these helpful videos !
thank you so much..love from Bangladesh 😍😍😍
wow this video is very well edited
wow, this video was amazing
Wooww superb class ✌️✌️✌️
Wow.clear explaining thank u miss.
Thank you, you are awesome!

@@ConfidentChemistry Thank you again .
8:20 Please I don't know how or why CHH tops CHHH
I thought CHHH has a higher atomic number than CHH
Help me out please
Same question i wanna ask as well?
she had to miscount there's no other logical explanation
Love it 😍
I love your channel. Subscribed you
Very nicely explained. I will recommend my students watch this!
amazing job maam
brilliant. thank you very much.
Thank you very much
thanks a lot ureally inderrate
Thanks so much madame live long and heathyl life
How is Chiral Carbon at left side is R??? This is S
Why did u not count HHH instead of CHHH???
Excellent effort highly recommended 🎉
sorry why for problem 2 do you have the second priority carbon in the ring connected to OO and C. I know its a double bond but I figured you'd just count 2 O's but you also count an extra C? Is this always the case? thank you for your advice!!
one carbon of the double bond is also connected to an methyl
Why is the bromid on the right an the CH3 on the left in the first example of the practice ? Would have drawn the bromid on the left as in the drawing and the CH3 to the right and therefore I got a R configuration. :/
Pls make more videos in organic chemistry...
i miss you ,you are > my professor

How can I access your slides

It was noice.
One question
In the aminoacid cysteine we have 4 different Atoms attached to the stereogenic carbon
1. N (NH3)
2. C(A) (CH2 - SH)
3. C(B) (COOH)
4. H
Apparently at first glance we see that N > C(A) = C(B) > H. So we have for sure that nitrogen is in first priority while hydrogen is in fourth
Secondly we are gonna compare Carbons A and B and we see that Carbon A is attached to 2 hydrogens and one sulfur (a.n = 18)
On the other hand we see that Carbon B has one double bond and one single bond with oxygen.
You write that to assign a priority to an atom that is part of multiple bond, treat a multiply bonded atom as an equivalent number of signly bonded atoms.
CO2 ---> CO3
But if we do that in the Carbon B we will have a greater atomic number than 18. Therefore the configuration of cysteine will be S and not R.
What am i doing wrong then??
merry me🤣🤣🤣🤣🤣🤣🤣
Thank you so much
