Dude, seriously. All semester long, I have gone without really understanding this. This seriously has been the only thing that has actually made me understand this. I'm my blown right now.
I was stressing out thinking I would be spending hours making sense of chair conformations, but this video taught it all in a matter of 5 minutes. Thank you so much!
THANK GOD someone can explain this to me! My lecturer is great, but I was just not understanding the positions of the exciting groups in chair conformation cis-trans isomers. Thanks!
Thanks for the help, had 5 different people explain it to me and never got it tell now. "Its pointed down, and the one pointing down at this position is the axial."
Hey! Generally, your reasoning is correct. However, problem 1 is a tough one in that the conformation with the two groups on the equatorial position is the more stable one, even though the largest group (tertbutyl) is the axial group. To see why, try drawing the Newman projection. In the Newman projection, you will see that when the tert-butyl is on the equatorial position, it "bumps" with the other two groups as well as the ring structure. However, when tert-butyl is on the axial position, it
only bumps with the methyl and ring structure. The chlorine group is further way. Because we have less steric hinderance, our chair conformation is more stable.
AK LECTURES Do you have a video where you explain how to identify the location of lone pairs? For example in which orbital would a lone pair reside...depending on the type of atoms and bonds involved.
AK LECTURES It is part of it. I was using a method to determine in which orbital is, say the lone pair of a =N- atom, which turned out to yield wrong results. I was wondering if there is an efficient way to identify the orbital in which the lone pair reside.
Oh I see what you're saying. No there isn't any quick way, but the electron configuration is part of it. First you determine what the electron configuration of the nitrogen atom is all by itself (1s2 2s2 2p3). Then you determine how many hybridized bonds it needs to form with other molecules. It needs to form three bonds to fulfill the octet rule, so three valence electrons are used to create three hybridized orbitals. That uses up 3 out of 5 valence electrons. The other two are the lone pair electrons in the 2p orbital.
quite a late reply but im sorry, I got a exam on Tuesday so this might be good practice to explain. his drawing was showing equatorial rather than axial because the "mountain peak" was going up, so it was axial the straight line would point up, his is equatorial down but he just drew it in a way that looks more axial than equatorial. which a professor might mark u down for of consider incorrect because it looks axial than eq.
thank you so much, organic chemistry is a class i need a lot of help on and as a poor college student i cant afford too much tutoring. this really does help so much.
Thanks was really struggling with this a bit. But watched your videos, went through the examples a few times, and got it. axial changes to equatorial and vice versa

3 minutes in and I already understand drawing chair confirmations than I did after multiple hours of a textbook. Thank you so much.
10 years after its release yet still the most helpful video on the subject ive found
Best video ever! Learned all I needed to know in a matter of minutes!!
Nadia Naghi Thanks Nadia!
AK LECTURES ❤
Nadia Naghi will u explain the 2nd one how down the group takes axial position ??
this video is not underrated, it just has quality viewers. No nonsense and straight up clarity of concepts
You cannot imagine how many videos I have watched of chair conformation examples, and this is the only one that has made sense to me. Thank You
fantastic job... best explaination on youtube
Thank you Matthew !
Dude, seriously. All semester long, I have gone without really understanding this. This seriously has been the only thing that has actually made me understand this. I'm my blown right now.
i went through countless videos trying to understand, you are my saving grace. thank u bestie
I was stressing out thinking I would be spending hours making sense of chair conformations, but this video taught it all in a matter of 5 minutes. Thank you so much!
Thank u mate, undernstading this take me 3 years. Like for you
This is my first comment on a youtube video in years, awesome job man! this would have taken me hours, Thank you!
Definitely one of the best explanations of this I have come across - struggled with this for hours. Happy I can finally tackle it.
5 minutes and it cleared up my doubts that were stuck in my mind for a few days. Thank you soooo much. Saviour ;)
Thank you so much sir , for giving best explanation..love from India 🇮🇳 ❤
Thanks Catherine! Glad to hear that
great way of explaining it an not being too complex about it,very simple =)
Thanks Eden
YOU HAVE MADE IT EASIER FOR ME TO UNDERSTAND THANKS
Wow in a 3 hour class couldn't understand anything but in this 6 minute video i understand perfectly! Thank you so much!:D
I'm here 10yrs later and it's still the best video ever
Literally only one minute in and you have answered something I️ couldn’t find in 3 other videos. I️ am at peace now 😌
92% on my organic exam partially thanks to you :D
dang wanna donate some brain cells lol
chair conformations truly are the bane of my existence
THANK YOU!!!!!! was so stressed about this in class because I didn’t understand… now I do! Thank you!!
This really changed my perspective on how to approach this! Such easy steps to understand. Thank you!
This is exactly what I was searching for, so simple yet so useful
Studying for an exam was completely lost before this video. Thank you very much it really helped.
Excellent explanations! Very thorough and clear. I had trouble making that out from the textbook, but you've made it simple. Thank you
BaldwinDylan You're welcome!
Amazing job, you really saved m'y year, thanks a lot
blew my mind.... made is soo simple and easy to understand
Wow... That was the most clearest lesson I’ve ever had on this
THANK GOD someone can explain this to me! My lecturer is great, but I was just not understanding the positions of the exciting groups in chair conformation cis-trans isomers. Thanks!
oliviapatterson1 You're very welcome Olivia, glad it shed some light on the topic! :)
I spent 3 hrs to study the chair conformations by myself and not understood. this 5-min vid helped me understand clearly tho.... wonderful
Great! You're welcome Minju
I have an exam in 2 days and you just saved my grade, thank you so much!
You're welcome!
Thanks for the help, had 5 different people explain it to me and never got it tell now. "Its pointed down, and the one pointing down at this position is the axial."
YOU ARE AMAZING THANK YOU!!!!!!!!!!!!!! YOU ARE LITERALLY THE ONLY ONE MAKING SENSE
Wow I was so confused in lecture today, but this video clarfied it up so much. Thank you so much!!!!
Most helpful video that I watched on Chair Conformations! Thank you!
This just saved me for my exam tomorrow, thank you.

Watching on 1st January 2023.
Awesome
I love these videos! Best chemistry help on the internet
I watched one of your videos for cell bio and I hated it. Now I watched this one and I LOVE YOU!!!!!
Thank you so much! I was having such a hard time with these questions. You are simply the best!

Thank you so much, greetings from germany
Dude just saved me before my final !!
Comprehensive and absolutely excellent. Thank you! Taught in the first 3 minutes what some take 40 minutes to cover. Thank you!
This video definitely helped me grasp the content in no time; thank you so much.
woowww, thank you very much i had been looking all video but i didn;t understood but this video convices me now i understand thanks sir
god bless you!!! I finally understand
only bumps with the methyl and ring structure. The chlorine group is further way. Because we have less steric hinderance, our chair conformation is more stable.
Thank you so much! The concept of the alternating ups/downs finally clicked with me thanks to your explanation!
XxHarvestPrincessxX awesome to hear! :) Gotta love those "aha" moments!
thank you. you explaned it so clear!!!!
This is one of the best explanations I have seen. Now I get it!
Zak Matew Thanks Zak! :)

Thank you Inês! I'm glad to hear that! :)
This is amazing! My exam is in 2 hours and you saved my ass. THANK YOU SO MUCH!
This video was really clear and easy to understand. Big help - thanks!
Thank you! This video was quite helpful!
IT was simple and to the point. THx
Reeally the best ever, was looking for something like that
Wow!! You are the best!!! I am so happy...
You've just saved me. Thank you very much for making this video!
Excellent video , please keep on posting with the examples it really helped
you're a life saver!!!
Shouldn't the methyl group on the last example be equatorial (pointing up) and not axial?
Melanie Reyes no it should be eq( down ), bcuz methyl eq(down) is attached to a Hydrogen axial pointing up after the flipping~
quite a late reply but im sorry, I got a exam on Tuesday so this might be good practice to explain. his drawing was showing equatorial rather than axial because the "mountain peak" was going up, so it was axial the straight line would point up, his is equatorial down but he just drew it in a way that looks more axial than equatorial. which a professor might mark u down for of consider incorrect because it looks axial than eq.
