@@user-eo1tw9ly8q With a model kit, set it up the same way he did, all red axial and all white equatorial. Then individually rotate each ring carbon so that the red becomes equatorial and the white becomes axial. Chair flips are just switching between axial and equatorial. You will notice that the direction (up or down) will always stay the same. For example, if a group was axial up, a chair flip will make it will equatorial up.
Oh my gosh, this helped me so much. I was able to build my chair conformation but I didn't exactly know what a chair flip was. This is so simple and easy to understand. Thank you for posting!
It was such a bizarre thing to understand when i had my lecture on cyclohexane, couldnt just fathom the concept with what is on the paper, until i saw the 3D model and got to flip the positions myself. This is such a good video, good revision for me to visualize the process again
I watched like 5 videos on chair conformations and i could not understand how the numbering of the carbons were done after a ring flip. Finally your video has helped me. Thank you
I've been watching your videos with the teaching company on organic chemistry. I'm happy to have stumbled upon your channel here to hear your additional insights & explanations. Thanks!
This is wonderful to hear! I'm so glad that you are enjoying the product that I created with The Great Courses. I'm also excited to say that I will be making another course with them next year! in the meantime, please enjoy the TH-cam channel :-)
Thanks for the feedback! I am very happy that you find my videos helpful. Please subscribe, like and share my channel as much as possible... that is the greatest thanks you can give!
+marley cat I'm so glad it helped! Thanks for watching, and check out my product with The Great Courses if you want to learn more about me! www.thegreatcourses.com/courses/foundations-of-organic-chemistry.html
Thanks for the help! I had a hard time trying to picture what I was supposed to be accomplishing with my model, but our professor kept asserting that we needed to use one to strengthen our understanding of the required concepts. It was a little weird doing it with a molymod kit, but it can be done.
My pleasure. Glad you found it helpful! Don't forget to check out my channel for tons of short videos and animations on organic chemistry topics! th-cam.com/users/chemsurvival
+Hallan Mtatiro Me too! I will never forget the first time I did this in front of a live class. Their reaction was breath-taking. Isn't nature amazing?!
It would kind of help if you rotated the model so we could see the top and bottom of the model and not just the sides. We see the sides all the time in the textbook 😅

Just be sure that you order a kit with at least six white and six red atoms, and you should be able to re-create the models in the video. There are some less expensive kits created by third parties which don't have enough atoms. I recommend the one in the nifty green carrying case. www.molecularvisions.com/Molecular-Model-Kits/Kit-1-ISBN-978-09648837-1-0-Organic-Inorganic-Organomet/prod_2.html
th-cam.com/video/lswaMuzyZZQ/w-d-xo.html Check this video out. Thought it focuses on one particular conformation during the transition, it might help you visualize the full conformational change better.
Yeah, the darling model kits aren't very good for much... except for making cyclohexane ring flips. Oh, and making you super confused and frustrated when you have to use it...

9 years later this vid id still saving students like me thank you sir for this
Glad to see the views still coming in! Best of luck with your studies.
it makes a lot more sense now though I wish you had flipped it more slowly
using 0.25 speed...still hard to see

I have only made chair-based videos so far, but this gives me a great idea for what to do with my lunch break tomorrow :-)
wow it iwas so hard to visualize this in the textbook. THANK YOU

A great video. Easy to understand "ring flip"
I finally understand the ring-flip! Thank you so much!!
This was a great and really helpful video! Thanks so much for making it.

Thanku so much sir..for explaining through model kit..otherwise it wasnt explained well by books...
This is 100% the professor who does the organic chemistry lectures for The Great Courses.
YES!!!!! That's me! :-)
This demo REALLY helped!
Thank you! It helped me a lot to understand.
great class sir
thanks for this video~
i finally got it!!
粘晉同 Awesome!
Thanks you so much sir i am from 🇮🇳🇮🇳 and it is so moch useful and educational for me
Glad it helped! Please like, share and subscribe to my channel!
the flip feel like magic; i had several David Copperfield moments
+Hallan Mtatiro Me too! I will never forget the first time I did this in front of a live class. Their reaction was breath-taking. Isn't nature amazing?!
Thanks this really helped!!
Did you have to do it so fast?
Thank You! You are awesome!
Any video where you explain the conformers of cyclohexane?
Really helpful, thanks!
It would kind of help if you rotated the model so we could see the top and bottom of the model and not just the sides. We see the sides all the time in the textbook 😅
Very good demonstration 👏 I'm also making content about cyclohexane.
Thanks for watching! Don't forget to like, subscribe and pass it on!
I will see what I can do for you!
I didn't understand
I have an exam in a weeeeeeeeeek
Could you tell me how did you do the flip ?????
Thank you so much!!!!
Chendrika Rao You are welcome! Please share my channel with your friends, teachers and classmates!!!
Will do. If possible can you make a video on naming of Quinones (IUPAC/ Common).
Thank you !
Thank you sir ...
what model kit would you suggest me to buy?
thank you
Glad to help! :-)
What is the name of the thingy that professor Davis is holding to demonstrate the flip?

+ChemSurvival Thanks!
Question! Where could I order or get me some of those ''darling models''? And what would it cost?
Search "Molecular Visions" on Google or Amazon and you will find many options!
Just be sure that you order a kit with at least six white and six red atoms, and you should be able to re-create the models in the video. There are some less expensive kits created by third parties which don't have enough atoms. I recommend the one in the nifty green carrying case.

thxx !!
I just put one up on the channel which covers the boat and twist-boat, which complete the set. Check it out!
darling model kit.. hahaha 😄😄
You flipped the structure extremely fast. It was hard to visualize.

Pace Bois here
thx i understood bbbb
wtf did he do
Ring flipping
Darling models ✌️😅 good name
can you gift me a good chemistry model please
Is everyone here in high school??
Yeah, the darling model kits aren't very good for much... except for making cyclohexane ring flips. Oh, and making you super confused and frustrated when you have to use it...
Skip to th-cam.com/video/6VUU-_JExMs/w-d-xo.html to see the flip.
There's no point in going so fast

flip it slower please
Thank you my good sir, It was troublesome imagining the ring flip, but you are a life saver.
