@@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.
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
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!
+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
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 RU-vid 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!
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.
+braindeadboner Fair enough, but that name is conventional so it isn't likely to be changed any time soon. Frankly, 'inversion' is a bit misleading as well (though not as much so as a 'flip'). I would call it a 'ring conformational inter-conversion' to be rigorous, but that doesn't roll of the tongue as well :-/
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! ru-vid.com
+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 😅
+bruno couto This is a so-called 'Darling' model kit by Molecular Visions. If you are interested in purchasing one for yourself, try the URL below. www.molecularvisions.com
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
ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lswaMuzyZZQ.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...
