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.

KZfaq 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!

wow this video is very well edited

Thank you so much for making these videos. They are so helpful!

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!

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 🎉

Thank you very much,I have no a word to express your knowledge

Amazing video, thank you so much! It simplifies the topic and explains it clearly

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)

You are legit amazing❤...finding your channel has made my day🌱

Very useful and clear! Thanks for sharing!

Thank you very much

Thank you so much for these helpful videos !

Love it 😍

Wooww superb class ✌️✌️✌️

i miss you ,you are > my professor

thank you so much..love from Bangladesh 😍😍😍

wow, this video was amazing

Wow.clear explaining thank u miss.

BEST VIDEO IN KZfaq!!!

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!!

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)

Thanks so much madame live long and heathyl life

I love your channel. Subscribed you

Thank you, you are awesome!

amazing job maam

Pls make more videos in organic chemistry...

brilliant. thank you very much.

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

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..

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🤣🤣🤣🤣🤣🤣🤣
