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!
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...
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!
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.
but then how do you know which direction to draw the first equatorial position??? ahhhhhh Dave didnt check comprehension we're all gonna DIE!!!!!!!!!!!!
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
+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.
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.
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
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!
You are such a great perSon. . you are such a great teacher. . .everything is going to be funtastic about you.... Plz...upload a video. on fractional distillation of liquid air and isolation of noble gases
Thank you very much for teaching how to draw this chair conformations correctly. I tried to understand this with my books and failed. Then I found this amazing video. 😊😊😊
actually equatorial and axial positions can tell u if they are cis or trans it is- for 1,2 carbon axial and equatorial will be cis to one another for 1,3 carbons axis and equatorial will be trans and for 1,4 axial and equatorial will be cis if at 1,2 carbon both hydrogens are equatorial/axial it would be trans relation if at 1,3 carbon both hydrogen are equ/axial it will be cis
눈누난나 안녕하세요! 한국 사람? It looks like you're learning english..Would you like some help? And I would appreciate any help with my 한국어 ㅋㅋㅋ Please reply to this if you're interested ^^
This is how I want my professor to be The statement about not relating cis trans to axial and eque helped a lot thanku professor u just got a new partial student and well as partial fan Haha remember fasan rule I can't be both at same time 😂
Thank you so much for those videos!!!!! Professor Dave is the best ! your explanation is super crystal clear =)))))) By the way, I like your hair! haha
After having seen this, I'll be laughing while thinking of 'bow tie syndrome' during my exam, lol. Anyhow, it's amazing how you managed to simplify this so much while keeping all the essence. Great work!

Was going to drop this class, then I found your channel. You present everything in a very straightforward and engaging way!
This helped so much that I want to get a tattoo of your face on my forehead.
i support this! if you do it, i'll give you one free hour of Skype tutoring.
omg wtf XDDD
you do Skype tutoring?!
😆😆
😂😂he are trying to summarize his emotions
This helped me a lot in my last minute struggle to understand this concept fully before the exam. Thank you so much!
Hi
Wow this is the best playlist on organic chemistry ever, I am not confused about a single thing!
the last minute comment about cis and trans not being related to axial and equatorial positions explained 5 hours of frustration and confusion
+soap2soap very common misconception! happy to clarify.
I still don't understand it. Can you explain it to me again? Thanks!!
@@ProfessorDaveExplains 12:33 ins't the cis-/trans-concept only applicable on structures with double bonds?
Nope, it applies to rings as well.
It's always the "Oh by the way" statements that save lives 😆

you are very clear and concise.
+JZoidberg that's all i've ever wanted to be!

Thanxz for making me clear
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.
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)
but then how do you know which direction to draw the first equatorial position??? ahhhhhh Dave didnt check comprehension we're all gonna DIE!!!!!!!!!!!!
Best 109.5 times from my teacher. Real professor in explanation 👌
Couldn't be any clearer! This channel is amazing! Thank youuuu!
+Amira Lam. my extreme pleasure! feel free to send questions.
This helped me in so many ways. Literally a godsend.
this is going to save my exam next week... thank you whatever that helped me find you!!!
WOW left me speechless this was such an informative and helpful lecture you're the best thank you !!
Perfectly explained, thank you so much for the clarification with cis and trans!
You have helped me more than you could ever know through gen chem, physics, and now organic chemistry. God bless you my friend.
Professor daniel will explain one day!
Hi
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
+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.
love the beginning with all the facial expressions! So creative prof. Dave
Very simple yet clear and comprehensive. Thank you!
Hello
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.
"Best explanation on RUclips ever"👍🙂
Very thorough and easy to understand! Thank you!
You helped me get through whole tough week at Uni . Thanks 😊
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
wow. Professor I love the way you teach thanks for this

Hello
thank you so much for all of your videos ...
literally helps me a lot. this guy is underrated!!
This the best Channel to learn Chemistry in a fun way.Thanks a lot once again for ur Efforts.
thank you so much i literally couldnt get my mind around the equatorial/axial dealio until now
Girl same I was giving up until I saw this
Thanks Dave! This helped me pass my O-Chem quiz.
Prof. Dave is the GOAT
I'm in love with you, litterally!!
Thank you for sharing! It really helps, even in France!!
definitely gonna rewatch but this time taking notes. You explained it so well thank you so much professor Dave.
it help my midterm quite a lot. Thanks!!!
You explained what my prof couldn't' t explain in an hour. Thanks a lot
Thank you so much, very kind of you to post this!
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!
Your videos are incredibly clear and concise! Thank you!
Extraordinary explanation, thanks a lot, You look loke a friend of mine from Italy.
You teach better than my instructor.
U are the best, dude.
Greets from Germany
Thanks a lot!!!! Cheers from Rio.
You are making it easy for me to understand unlike my lecturer
I wish I could like a video more than once. Thank you for actually explaining it 💖
You are such a great perSon. . you are such a great teacher. . .everything is going to be funtastic about you....
Plz...upload a video. on fractional distillation of liquid air and isolation of noble gases
Your videos are the best! Thank you so much for taking the time to make them because they are extremely helpful :)
thank you sooooo much ! it helped me so much ! glad to have you to learn my chemistry lessons ! hello from france :)
1 hour to my exam and u saved my life❤
Thank you! I thought the chair conformation simply rotated when it flipped up until now.
Thank you so so so much! You explain things so clearly
dude keep up the legit work!!!
Thank you very much for teaching how to draw this chair conformations correctly. I tried to understand this with my books and failed. Then I found this amazing video. 😊😊😊
Best explanation ever my man ❤
If Jesus was a professor, he'd be like you 🙏 thanks for saving our grades every time, no video on RUclips is as straightforward and concise as yours
Great videos! I'm glad I found you on here, I subscribed and will let my friends in Organic Chemistry know about your channel!
Thank you Prof Dave ! Finally I know it 😆
thanks a lot prof,,
this tutorial help me more than i need ,clear and very easy
Iam lucky to find this video,,
OMG thank you so much. only now I understood this after all these years!
actually equatorial and axial positions can tell u if they are cis or trans it is- for 1,2 carbon axial and equatorial will be cis to one another for 1,3 carbons axis and equatorial will be trans and for 1,4 axial and equatorial will be cis
if at 1,2 carbon both hydrogens are equatorial/axial it would be trans relation if at 1,3 carbon both hydrogen are equ/axial it will be cis
Yes, it depends on the location. So the terminology is not inherently linked.
Professor Dave you are priceless.
This a great video. Your channel is the best!
Hi
Note that we usually use the chair 1 conformation, and start labeling carbon 1 at the bottom right.
you are a legend my dude
This man single handedly carries us
Thanks from south of Korea:)
눈누난나 안녕하세요! 한국 사람? It looks like you're learning english..Would you like some help? And I would appreciate any help with my 한국어 ㅋㅋㅋ
Please reply to this if you're interested ^^
you're awsome professor!! Hats off!! you made me clear:)
Another ace video Prof! Thanks so much 🦊
You're the man! Thank you so much!
"Let's talk about cyclohexane chair conformations." Sure, why wouldn't we?
This is how I want my professor to be
The statement about not relating cis trans to axial and eque helped a lot thanku professor u just got a new partial student and well as partial fan
Haha remember fasan rule
I can't be both at same time 😂
this guy is a total complete boss.
ur video saved my life thx
This stuff was frustrating me so much, I might've just flipped a chair!!!
But thanks for clearing that up. My chair is fine now.
Thank you so much (Sun 20 Dec 2020, 2:58 AM)
teaching method is best .l like so much
Thanks!!
Thanks so much.
Amazing

YOU ARE AMAZING. Thank you so much!!!!!!
very good teaching please enontiomers and diantiomors
+Reddy Viswanath i did all that! take a look.
thank you! very helpful
You’re good at organic
Hi Professor, I want to learn from basic lessons. Should I watch the organic chemistry playlist in order or is it shuffled and I have to choose it?
All my playlists are ordered in a very deliberate sequence, watch from start to finish.
