Cyclohexane Chairs

Cyclohexane makes weird shapes! The most important is the chair conformation. Here we will learn how to draw cyclohexane chairs, how to flip them, the difference in energy between the two chair conformations, and between axial and equatorial substituents. Chairs are easy place to lose points on exams if you don't draw them just right!

Here we are again, night before the exam. Will I pass… or will I watch a whole series of Professor Dave explaining chapters of material intended for moderate consumption in a matter of hours. Godspeed gentleman.

[@inversedq2190]

Did you pass?

[@chickenwang8786]

we need an update lmao

[@pitachipenthusiast]

Was going to drop this class, then I found your channel. You present everything in a very straightforward and engaging way!

[@xoxoYUMoxox]

This helped so much that I want to get a tattoo of your face on my forehead.

[@ProfessorDaveExplains]

i support this! if you do it, i'll give you one free hour of Skype tutoring.

[@aimanshaheen973]

omg wtf XDDD

[@elisabethrauschecker8310]

you do Skype tutoring?!

[@chiragchandnani310]

This video is worth millions....it helped me a lot....my exam's gonnna commence in about 2 hours and this video just nailed it... Kudos to professor dave!

[@wtbgothgf]

This helped me a lot in my last minute struggle to understand this concept fully before the exam. Thank you so much!

[@mehwishkerio4094]

Hi

[@dude9864]

Wow this is the best playlist on organic chemistry ever, I am not confused about a single thing!

[@nu.wa.n]

you are very clear and concise.

[@ProfessorDaveExplains]

+JZoidberg that's all i've ever wanted to be!

[@sheenaverma1996]

Thank you very much for you help, I have my organic Chemistry exam coming up and the past couple of days I have been just watching your videos. They are so helpful and I actually understand, you taught me a whole semester full of organic chemistry through your videos. Much appreciated!

[@suhaylamwinyi8555]

Thanxz for making me clear

[@aguilacoco7652]

10:22 "Now this chair it's going to be THE MORE ENERGETIC..." internally freaking out "... favorable" filled with relief. I love this channel so much, your explanations are amazing.

[@SyenPie]

Jesus christ... I've said it again and I'll say it now, you are by far the best educator for the sciences on this platform. This video in particular... it's absolute perfection. Actually humanly physically impossible to have presented it any more clear. Thank you as always...

[@kiandebeste5455]

A tip for knowing which direction to draw equatorial positions: Make sure the line is parallel to the bond 2 bonds over (either direction works)

[@NewWesternFront]

but then how do you know which direction to draw the first equatorial position??? ahhhhhh Dave didnt check comprehension we're all gonna DIE!!!!!!!!!!!!

[@soap2soap]

the last minute comment about cis and trans not being related to axial and equatorial positions explained 5 hours of frustration and confusion

[@ProfessorDaveExplains]

+soap2soap very common misconception! happy to clarify.

[@yongchinchong3787]

I still don't understand it. Can you explain it to me again? Thanks!!

[@luftatmer]

@@ProfessorDaveExplains 12:33 ins't the cis-/trans-concept only applicable on structures with double bonds?

[@ProfessorDaveExplains]

Nope, it applies to rings as well.

[@cowslane1]

It's always the "Oh by the way" statements that save lives 😆

[@GeniePak]

this is going to save my exam next week... thank you whatever that helped me find you!!!

[@AmiraDreams]

Couldn't be any clearer! This channel is amazing! Thank youuuu!

[@ProfessorDaveExplains]

+Amira Lam. my extreme pleasure! feel free to send questions.

[@ts37924]

WOW left me speechless this was such an informative and helpful lecture you're the best thank you !!

[@Psychedt]

You have helped me more than you could ever know through gen chem, physics, and now organic chemistry. God bless you my friend.

[@Psychedt]

Professor daniel will explain one day!

[@mehwishkerio4094]

Hi

[@ucf_zn]

Best 109.5 times from my teacher. Real professor in explanation 👌

[@elisabeth9608]

Thank you so so so so so so much I cannot stress how much this helped me. You are so clear and concise and I loved how you showed the conformations side by side to compare them.

[@diemdinh73]

love the beginning with all the facial expressions! So creative prof. Dave

[@hamdaesam5364]

This helped me in so many ways. Literally a godsend.

[@trudymatt7335]

I signed in just to tell you thanks...like really this helps soooo much...and the rest of your videos....thank you great person e.e

[@ProfessorDaveExplains]

+Trudy Matt thanks very much!

[@mehwishkerio4094]

Hello

[@ZippyandOllie]

Perfectly explained, thank you so much for the clarification with cis and trans!

[@crushcollegechemistry]

Very simple yet clear and comprehensive. Thank you!

[@mehwishkerio4094]

Hello

[@miltonincsw]

Hi Dave! Loved the way you explained them! Can I classify the conformations with their responding strains as followings? Staggered = no torsional strains Anti = No Strains Gauche = Steric Strains Eclipsed = Torsional Strains

[@ProfessorDaveExplains]

+Milton Chow hmm, I've never really thought of it that way, but i suppose it makes sense. however, let's just say that anti involves the least possible amount of steric hindrance, though not necessarily zero.

[@bradd777]

Very thorough and easy to understand! Thank you!

[@princessTJrulz]

You helped me get through whole tough week at Uni . Thanks 😊

[@N1ckelD1me]

thank you so much i literally couldnt get my mind around the equatorial/axial dealio until now

[@سمرمحمود000]

thank you so much for all of your videos ...

my god you explained ring flip so much better than my professor. i kept making the mistake of when you ring flip the carbons don't stay in the same place

[@siddharthsingh5169]

wow. Professor I love the way you teach thanks for this

[@Tamaraaudeh]

literally helps me a lot. this guy is underrated!!

[@bisharofarah950]

definitely gonna rewatch but this time taking notes. You explained it so well thank you so much professor Dave.

You explained what my prof couldn't' t explain in an hour. Thanks a lot

[@meganscanlon9560]

Thank you so much for these videos. I just started O Chem and my professor was NOT explaining this in a way that made sense. I thought the chair analogy had to do with the hydrogen bond angles or something, gosh! That's how he made it sound!

[@yonipool8683]

Thank you so much, very kind of you to post this!

[@brigitteg2725]

Thanks a lot!!!! Cheers from Rio.

[@evasigala7391]

Thank you! I thought the chair conformation simply rotated when it flipped up until now.

[@squidwardtentacles3023]

Professor Dave you are priceless.

[@tunneltrance]

Great videos! I'm glad I found you on here, I subscribed and will let my friends in Organic Chemistry know about your channel!

[@ochako1483]

I wish I could like a video more than once. Thank you for actually explaining it 💖

You are making it easy for me to understand unlike my lecturer

[@yashverma2420]

you're awsome professor!! Hats off!! you made me clear:)

Another ace video Prof! Thanks so much 🦊

Note that we usually use the chair 1 conformation, and start labeling carbon 1 at the bottom right.

1 hour to my exam and u saved my life❤

Thanks so much.

i did, in this video

@@ProfessorDaveExplains I meant about other conformers like boat, twisted boat and half chair, about their order of stabilities.
