Your videos being me SO MUCH joy!! You are incredibly passionate about teaching, and it shows! I always come to your videos distraught and overwhelmed and leave them feeling so calm and satisfied. Your way of presenting information is so effective. I love all the metaphors, demonstrations, and connections you make. Your voice is also so soft and soothing. It makes me feel happy and less stressed. I feel much more at ease learning from this channel. Your videos are one of the best things to happen to undergraduate science resources.
Thank you so much for the great feedback Becca. I am glad to be of help to everyone having hard time with OChem. Thank you for subscribing! :) I wish you all the best!
My major is Medical Laboratory Science. After completion of the program and passing a registry exam I will be a certified Medical Laboratory Technologist. I'm thinking of going into hematology and blood banking.
Madam, this video is the best video ever on chair conformations of cyclohexane. I am a Chemistry Faculty for JEE and NEET(in India). I have used this video to explain chair conformers to my students as currently all lectures are conducted online due to the pandemic. Thank you so much for such amazing videos where explanation is lucid and interesting.
Marvellous! This topic was taught by so many teachers and I thought that the problem was with me that I did not understand, but seeing this, I think I finally understood. Thanks a lot!
The first time I did watch your video was when I subscribed to your channel. I can't deny that I owe you a lot of thanks. Love you straight from Ghana.
wow, this vid was made when i was still in 6th grade. now im in my sophomore yr in college and taking up orgchem1. this vid really helped me alot. thank u :))
Its a very good way to study the organics. Never actually knew the true meaning of chair,boat, twist confirmation, but this video helped me to understand it clearly. Thanks.
Thank you so very much for this! I really can’t imagine this darn chair and boat thingy during my review. You have no idea how much you made our lives easier!
@@Leah4sci Hey, Leah! Since my comment, I have graduated with honours from my program and minored in Chemistry. I am now doing my Master’s (not Chem related but my Organic Chem grades sure helped getting me where I needed), and every now and again I see one of your videos on my timeline, and I smile the biggest smile there is. You kept me company for many nights. Thank you for everything.
Thank you so much for your precious lecture 😊 Can I ask you a question? Why Nitrile which is axial position is more stable than methyl? Could you tell me the reason? 😭
I'm sorry, but I don't offer tutoring through TH-cam comments. For help with this and more, I recommend joining the organic chemistry study hall. Full details: leah4sci.com/join
Great explaination..!! Why don't we place the bulkier groups on the adjacent axial positions. They will face in directly the opposite directions, hence will be more stable
Ur just amazing and I would say that ur the best teacher I have ever got.......literally nobody can explain with so much clarity....luv from india...😘🥰🤗😍
Wow. Ur illustration is just amazing. you have made this concept much more easier for me. I think if u were my chemistry teacher in my school then i was definitely fall in love with chemistry.......as i hate chemistry due to theses difficult structures
Amazing ....it is jst a awsm vdo ...now I am able to think the structures of boat and chair conformers more easily .... wonderful..keep us offering these videos ... it's very helpful ☺️☺️☺️👏👏
I'm not sure if it's correct to do this, but my prof taught us to draw equatorial substituents parallel to the bond coming off of the "alpha" carbon in respect to the substituent. (Can we use the alpha, beta etc. nomenclature for non-carboxyl groups?)
Both Leah and your professor are correct. If you follow Leah carefully in this video you would realize that both are correct. But what your professor had taught you may come handy while carrying out reactions at cyclohexane.
Zee Shan I know that Leah said that it doesn't matter on which side you draw the bond, but I thought it was better to have a set guideline because there is less room for confusion.
I haven't heard of it being taught this way and so here is my advice for any trick 1- make sure you understand the logic behind it and that it makes sense 2- only once you confirm #1 above, memorize the trick
Hello, what about 1,2-dimethylcyclohexane with both methyl groups in axial positions, because one is pointing upward and the other downward, wouldn't that be pretty stable too as the groups are pointing in opposite directions
Thanks for your question! The conformation in which both methyl groups are in the equatorial position would still be the most stable conformation. This is because substituents in the axial position have more unfavorable steric interactions with other axial atoms (in your case, hydrogens) on the same side of the ring. When the methyl groups are equatorial, steric hindrance is diminished.
Wouldn't the second molecule in the last example be more stable in the diaxial position, because they would be pointing directly away from each other 180 degrees?
I'm sorry, but I don't offer tutoring over TH-cam comments. For help with this and more, I recommend joining the orgo study hall. Full details: leah4sci.com/join
Hi Leah, Would we be able to determine stability of chair conformations even if we have one group that's axial and the other equatorial or does this depend on the type of group (bulky group) and whether that's on an equatorial or axial position ( equatorial being the most stable) ?
Yes, axial substituents experience steric strain with other axial atoms on the same side of the ring. In the equatorial position, steric strain is diminished.
plz guide me how can i made this model with the help of cupper wire actually my teacher me a projection that make chair conforamtion model ans show filpping with help of cupper wire
This is the actual way to study organic chemistry ! I never knew the actual meaning of that chair and boat before I saw this video.
Glad the video helped you understand the topic better!
This is the best explanation so far for this topic I'm literally screaming how every question in my mind was answered lol
Yay! that's awesome! I'm glad the video helped! All the best Bey Zee! :)
8 years have passed, and this is the best explanation of chair conformation i have ever watched,
Thank you ❤
You're welcome and happy to hear it's standing the test of time!

I understand that. I love orgo more and more each year
now i understood , neither the lecturer nor the practitioner helped me , thank you !!!
Glad it helped!
you did a crazy good job at explaining this
Thanks!

It's typically the teacher, everything is understandable
I am a undergraduate student, it is more helpful to understand 🪑 conformation. Thank you mam. Love from India.
You're welcome! Glad it was helpful!
takeaway : Axial substituents are highly unfavored, equatorial substituents are highly favored.
nice
Man, Leah, you are just amazing, you take all of the stress out of this subject thank you so much.
You are so welcome!
This was the best explanation of the chair conformation I have ever seen. I am so incredibly greatful!

Which one would be more stable between the two if in the first structure the methyl was on carbon number 4(AXIAL)?
A conformation where both groups are equatorial will always be more stable than one with the same groups in an axial position.
Great explaination..!!
Why don't we place the bulkier groups on the adjacent axial positions. They will face in directly the opposite directions, hence will be more stable
Thanks! Your question, at which part of the video? timestamp please.
Your students are in good hands!
Thanks! I like to think so.
Thank u for the amazing visualisation explanation ❤️❤️❤️

THANK YOU SO MUCH LEAH NOW I UNDERSTAND
Glad to help! You're very much welcome.
Wouldn't the second molecule in the last example be more stable in the diaxial position, because they would be pointing directly away from each other 180 degrees?
At which specific point in the video?
Thank you so much..
It helped me a lot..I'm gonna watch all of your videos..
You're very welcome!
mam u said stable compounds are unreactive but benzene is stable yet it is reactive why?
I'm sorry, but I don't offer tutoring over TH-cam comments. For help with this and more, I recommend joining the orgo study hall. Full details: leah4sci.com/join
But benzene is aromatic compound how is it related to cyclo compounds
Hi Leah,
Would we be able to determine stability of chair conformations even if we have one group that's axial and the other equatorial or does this depend on the type of group (bulky group) and whether that's on an equatorial or axial position ( equatorial being the most stable) ?
I think you've got the idea! The preference would be for the bulkier group to be in an equatorial position and the less bulky group to be axial.
Just in time lol. Need this for my Friday quiz.
Happy to help!
Thanks a lot mam... Before watching this video I got confused between axial and equitorial positions... But not anymore...
So happy to hear that and to help!
Too helpful 👍
Glad to hear that!
Why did you number the chair conformations that way?
Unless you're numbering for nomenclature, the direction doesn't matter so long as you're consistent between structures
Is the strain the axial substituents experience steric strain?
Yes, axial substituents experience steric strain with other axial atoms on the same side of the ring. In the equatorial position, steric strain is diminished.
plz guide me how can i made this model with the help of cupper wire actually my teacher me a projection that make chair conforamtion model ans show filpping with help of cupper wire
Why not buy a pre-made model kit? Leah4sci.com/kit
