Newman Projection Stereochemistry R & S Trick: Chirality Vid 7

[@HelloGudbye93]

I am so unbelievably grateful to know that if I have a question/don't understand something with orgo, I can come on your channel and get a clear, simple explanation in less than 10 minutes. Thank you SO much!

[@Leah4sci]

Oh wow, so happy I could help!

[@nanothefruit8063]

I wonder how much effort you put in BUT BELIEVE ME YOU ARE DOING A GREAT JOB I RESPECT YOU A LOT YOU ARE DOING WHAT PROFESSOR'S CANT may God always bless you!!

[@Leah4sci]

Thank you for your kind words!

[@tyephan7475]

I was having so much trouble doing these types of questions until I saw this video - thank you so much!! This is so helpful.

[@Leah4sci]

You're so welcome!

[@julialinton6903]

Your videos have been a key tool in my studying for organic chemistry, thank you so much.

[@Leah4sci]

Good to know the videos helped! :) Thank you for subscribing!

[@gladnessmanana4568]

The reason why I choose your videos over others is not only because you explain well but also because you have such a beautiful voice and great method of presentation!

[@Leah4sci]

Aww thanks so much, glad you like my videos!

[@annybarona7976]

You are my hero !!! I just started organic chem and it hasn't been that easy for me .. But your videos are so effective I love it ! Thank you so much

[@Leah4sci]

Glad I could help!

[@stanle6602]

OMG WHATTTTTT. thank you i was having trouble drawing the whole structure and trying to flip everything!!!!!

[@Leah4sci]

You're very welcome, so happy to clear things up for you!

[@josphellihsilak4588]

the swap method ought to be the standard for teaching R/S. I have shown my classmates and their minds bend. So good.

[@Leah4sci]

Glad it helped!

[@abulfazalwashim304]

you are a great teacher, voice is very clear and easily understandable, carry on your jobbbbbb

[@Leah4sci]

Thanks so much, and I hope to keep at it for years to come

you saved my life i love organic chemistry now. Thank you so much i wish i found your videos earlier

[@Leah4sci]

So glad to hear it! You're welcome.

I felt totally lost, but thanks to you i understnd now! Seriously, you are so much better than the professors at my uni! :)

[@soundsofnaature]

absolutely out of this world.thanks a lot

[@Leah4sci]

You are welcome!

[@StacyO.]

Very helpful thanks... But couldn't u have used the reverse method for when the no 4 is forward instead of the swap like in the Cahn- Ingold -Prelog method?

[@Leah4sci]

There are multiple ways to solve problems like this. The key is to understand how to do it right, then learn a shortcut you’re comfortable with to help save you time.

[@n.i288]

Thanks for all these videos! Very helpful!

[@Leah4sci]

You're so welcome!

[@hanialkhatib6855]

Does the 2 swaps apply also for the rear one too if the one with least priority is not in the middle? Great expalantion btw!

[@Leah4sci]

If you are looking at the rear carbon's stereochemistry then yes, same thing

[@hadeerrashad5486]

I can't thank you enough!!!!! Thank you sooooooooooo much for making this video!!!!

Hey Leah,Saba here. I am a big fan of yours and organic chemistry seems simple and easy due to ur logical teaching! Thanks. Which hardware and software are you using for making these videos? Kindly respond!

[@churos500]

Thank you so much ! Everything is clear

[@Leah4sci]

You're welcome!

[@Shreddingg]

so confused as to why we reversed in the last one. I thought you do not reverse if the least prioritized group is already forward?

[@Leah4sci]

no, exactly the opposite. Goal is to have the lowest priority in the back

[@BeesanArda]

THANK YOU THANK YOU THANK YOU!

[@Leah4sci]

You're very very welcome! :)

[@RedFactionM41]

Hey would you mind doing more Fischer projection examples. I'm not getting it.

[@Leah4sci]

You can check out additional resources at leah4sci.com/fischer

[@kemyaalsaydla7451]

Yea well but on your first example, if you draw the sawhorse projection, Br will be dashed and OH and CH3 will be planar and CH2CH3 will be wedged, and it will be R but the 4th group will NOT be into the page/dashed and hence it will be S!

[@Leah4sci]

At which part (timestamp) of the video are you referring to?

[@thisismyoutubechannel]

literally....thank u SO much

[@Leah4sci]

you're welcome :)

[@santhoshsamrudh]

How many times any two groups can be exchanged in a fischer projection so as to get the same compound?

[@Leah4sci]

I'm sorry, but I don't offer tutoring through KZbin comments. For help with this and more, I recommend joining the organic chemistry study hall. Full details: leah4sci.com/join

[@heleisysubervi9868]

im confused, how do you know when to do the swap?

[@brandonzarate2736]

swap when #4 is on the plane. If #4 is coming toward you, flip rotation

[@Leah4sci]

I teach the swap method in detail here: leah4sci.com/chirality See video #4

[@anuragkrit7948]

can we do the last example by swap method?... Please help me ... I am confused

This is an Organic Chemistry channel. It's amazing that you are learning stereochemistry in high school! Hope the video helped. :)

[@MuhammadBilal-fp2gq]

That doesn't apply to a bit more complex Newman projections with two chiral centres. I tried it, didn't work. For that what I do is to convert Newman to Fischer projection and then determine the configuration. Is there any easier pathway than this? Btw I have an exam tomorrow and it'll be too late for me. But that may help anyone 😊

[@Leah4sci]

I've done it for more complex Newman with multiple chiral centers as well. The key is to understand how you're looking at it

[@QuickSilver442]

Can we convert to Fischer Projection?

Yes, of course! Watch this video for my tricks on how to convert Newman projections to Fischer projections: kzbin.info/www/bejne/gXSyoaakoapjaM0

thank you

[@samazuma6745]

How is the last example S?

[@Leah4sci]

As I explain in the video, when #4 is forward you reverse the direction. 1 -> 2 -> 3 goes clockwise, reverse to give you counterclockwise for S
