R,S Configuration Problems

[@zahrashah5165]

Thanks for clearing this up using aromatic rings. The other videos only show simple branch chains

I've been searching for days about relevant videos for getting the pro R and Pro S configuration of this kinds of chemical structure. I'm so lucky that I found your video. Thank you and good job!

[@CJSReview]

Thanks, and glad you liked the video!

[@Save.Palestine.]

Perfect explanation! Well done, keep it up. You saved my time & cleared every confusion.

[@CJSReview]

[@munibali2242]

The use of the right-hand rule was brilliant. Can you make a video about drawing enantiomers and visualizing them in 3D (the swap method)?

[@CJSReview]

I have always used the right hand rule, but using the swap method could be a potential video later on. Glad you enjoyed the video, and thanks for the suggestion!

[@Sauravadi]

It was really helpful,sir. Upload more problems like this. A lots of thanks.

is there any exception to this method?

Hi, based on what I remember, I don't recall any major exceptions. That being said, I encourage you to watch the other videos in the series for more examples since they'll give a more comprehensive picture. Thanks for watching!

Deuterium has atomic number of 1. Please rectify it. For isotopes we use atomic weight.

[@CJSReview]

I see your point, since atomic number=number of protons and deuterium (2H) has 1 proton and 1 neutron, so its atomic MASS would be 2, not the atomic number. Thanks for the correction

Hello, hope you can get to this question today, but why doesn't the hydrogen have to be sent to the back on example 2 Thank you!

[@CJSReview]

Hi sorry, not sure what Hydrogen you’re referring to

[@zahranoor4130]

Sir i have a question plxxx.....sir if Hydrogen is not shown in a ring and we have two chiral carbon in a ring so hydrogen will be always away from us????

[@CJSReview]

Hi, I believe that if H is not shown and you want it pointing away, make sure that if there’s another chiral center that it’s pointing towards the page. Let me know if you need more clarification.

Which book u prefer for organic chemistry

[@CJSReview]

In undergrad, we used this book (www.amazon.com/Organic-Chemistry-William-Brown-Lawrence/dp/084005498X) although it was an older edition. Overall, I did like it and would recommend it. If you want more practice, there is a companion book with study problems (www.amazon.com/Student-Solutions-Iverson-Anslyns-Chemistry/dp/1111426813/ref=pd_sim_14_1?_encoding=UTF8&pd_rd_i=1111426813&pd_rd_r=ed177775-7386-11e8-9ab7-39985758a02b&pd_rd_w=U319M&pd_rd_wg=9NWf0&pf_rd_i=desktop-dp-sims&pf_rd_m=ATVPDKIKX0DER&pf_rd_p=7967298517161621930&pf_rd_r=E1GQ6XTK51ECZ4CSW8GY&pf_rd_s=desktop-dp-sims&pf_rd_t=40701&psc=1&refRID=E1GQ6XTK51ECZ4CSW8GY).

[@queennmo]

you made a mistake the last one is an (R) Configuration since its in the clockwise direction.

[@CJSReview]

When the Hydrogen is pointing out of the page (black wedge), you switch the configuration if you're using the clockwise vs. counterclockwise rule. So yes, you would think R at first because you go clockwise, but because H is pointing out of the page, you switch the R to the S. This extra step can be avoided in the method that I use in the video. www.chemistrysteps.com/how-to-determine-r-and-s-configuration/#:~:text=If%20the%20arrow%20goes%20clockwise,the%20absolute%20configuration%20is%20S.

right hand rule is superb idea i liked it thank for this video

[@CJSReview]

Thanks, glad you liked it!

[@elias1376]

@@CJSReview i think the hand rule is just too gimmicky. Just teach that the rotation has two directs. R and S. R moves clockwise and S is counterclock wise. I think of it as R = Right. But great video! Thanks for the practice.

[@CJSReview]

Everyone has a different way of learning, but I’m glad you enjoyed the practice. Thanks for watching the video.

[@BIKERGIRL_UK04]

Use of right hand 👍 Thnks But Deuterium has atomic no 1 not 2.

[@CJSReview]

Deuterium has a mass number of 2 since it has 1 proton and 1 neutron, and atomic number is the number of protons (and it only has 1). Thanks for the catch! I appreciate it

Y ether oxygen not chiral

[@CJSReview]

Only Carbon can be a chiral center, but what I was trying to point out in the video is that if carbon is attached to 4 different “things” (for example, it is attached to a methyl, an ethyl, a hydroxyl group so OH, and a hydrogen), this would make the carbon a chiral center.
