Thanks for all of your videos. You are the reason I got an A in my organic chemistry course. You explain things better than my college professor who is the head of the chemistry department! Way to go!
This is actually more useful than my professor at uni!!! You explained it so well and made it so much more understandable. Thank you so much for saving me hours of going through my lecture notes!!!
i want to say i love you so much for all your videos. I have a terrible professor this semester for organic chem and was struggling until i found your videos. thank you so much.
Converting it to a lewis dot (i think that's what that is) before diving straight into the newman makes it SO SO SO much easier for my brain to see! Thank you so much for that method, it's foolproof for me!!! I never would have gotten it without that trick because I have trouble visualizing things. THANK YOU!!!!
It's a shame that dislikes are no longer publicly visible, as that would've shown that this is an actually usefull and great explanation of the exact subject matter in a world of bad, slow, subject-irrelevant or otherwise lacking tutorials.
Properly explained! Really enjoyed it 😀 We could also make Saw-Horse Projections and just condense it's structure by joining the front and back Carbon atoms to get Newman's!
Hi, Any ideas for 18:12? My guess (without doing too much research yet) is that molecule 3 is the highest in energy relative to the other 2, given the numbers. Would you say that’s right, or do you suggest I do more research? Thanks, Rina
Hi I have a quick comment at6:42 minutes of the video at structure number 4 of Butane Newman you draw 14 hydrogen and 4 carbon is it for different molecule confirmation because I thought we draw a structure forc6H8. thanks I always benefit from your videos in science.
I wish he would release the full version. These videos would really help. I wish I could send $10 a month but I don't have that luxury. I don't understand why he can't get sponsorship.
@Sushiirull The content isn't free if you need to pay $10 a month to see more examples or better explanations ... Hopefully you're willing to leave this as it is.
is it not possible to put an ethyl group directly behind a methyl group on the top? 16:30 cuz then there'd be another solution. And I'm also confused if a methyl and ethyl group can change their order just like this ... ? one time, the methyl group is on the right side of the ethyl group, the other time it's on the left side. The substituents should just rotate, not change their places, or is it agreeable? I would be glad if someone could explain!
@@pauludom you are looking it from a different perspective. If anyone wants to learn properly he/she will have to study it correctly to understand.otherwise there will be a confusion. Think it that way.
In Which class does your teacher or professor teach this topic in your nation??? In India, In competitive approach it's Highschool 1st year i.e. class 11th Topic. . Thank you for wonderful explanation 😊.
Can you please do more videos about H-NMR spectroscopy and C-NMR spectroscopy as well as gas and HLPC chromatography, I really need some exercises and questions about these topics as soon as possible because I am not able to find some unfortunately
21:07 Why is comformation at the right corner more stable than the one at the left corner if they both have one gauche? How do I determine which one is the most stable of the two? I know that the most stable must be the one with the lowest potential energy but don't the two of them have the same potential energy? Or am I wrong? Do I have to do some steps to solve it? D:
I didn't get you, did he said that the right one is more stable than the left one? 20:58 he said, both the conformations are actually same with same potential energy, so you can choose either of them as they both are same but not the middle one
It's simple. All you have to know is this law is only applied in symmetry questions like cylinrcal or spherical symmetries. It's much easier than coulomb's law.
i feel that is so saddening that i have to come to youtube to learn material thats gone over in class rather than actually learning the material in class
The values are in kj/mol 3.8/gauche = H-H 4 = CH-CH 6 = CH-CH3 11 = CH3-CH3 Finding the energy between those two groups depends on conformation (staggered or eclipsed). In eclipsed formation the H and Ethyl group are aligned (so 0 degrees apart). This energy required needs to be measured but would typically be between 4-6kj/mol. It is higher than the H-CH3 eclipsed rxn which is 4kj/mol just due to the size of an ethyl group versus a methyl group. In staggered conformation (or gauche conformation), the hydrogen and ethyl are 60 degrees apart. This energy value would be slightly lower than the eclipsed formation (again needs to be measured) at a value between 2-4kj/mol.
How are low energy confirmations calculated, and if it can be done by hand, why can’t people find low confirmations of low energy of complex molecules? I understand it’s a calculation problem, but why is it hard to know what the low energy confirmations are with more complex molecules? Is it a random sample, and you just have to go through each confirmation to determine it’s angle and energy level?
Why is it near impossible to just determine only the finite number of low energy confirmations for complex molecules? And does the angle determine the energy level, or is the angle considered, but it’s matters where each atom is in Three-dimensional space?

I just started how tf u get an A big props. Wish me luck.. from Purdue
@@Djmheat6 Yo. I'm here too from Purdue in orgo ✌
@@Djmheat6 same here
They teach this in college?
EDIT I FINISHED WITH AN A!!!
Why is it that TH-cam, a free resource, teaches me better than the class I'm paying money to attend?
This is actually more useful than my professor at uni!!! You explained it so well and made it so much more understandable. Thank you so much for saving me hours of going through my lecture notes!!!
There's a special place in heaven for this feller

Wonderful explanation. I learned this within just few minutes. What an amazing teacher you are!! Thank you very much!!!
Thanks for your explanation
Wonderful explanation for the confirmations of alkanes
Hey at 6.30 there was a mistake on the rear 2 attachments for eclipsed butane you put 2 methyl groups where there should be hydrogens!
This is the clarification I was looking for in the comments, thanks
Yup at 6:30 👍🏻
Yup. Wasted 10 minutes figuring it out.
Yh...sure about that one ....have realised it too
Been looking for this comment
My final exam is on saturday and I've been hella confused by this topic. Thank you for teaching us this!
CHEM 123
@@tayamccartney66 EYYYYYY
Mine is on Monday
It's Sunday btw😅😅
You’re the best tutor for me. Thx for your best explanation 😍
I am having an Organic Chem test today. Will most def help!
I was failing but then I found you and was able to pass thank you so much.
I love ur videos. Like purrr we love a smart man😌
You're a game changer. I have understood this way better than l could have with my lecture.🎉🎉🎉🎉 Thanks
am i missing something or did you draw the number 4 conformation here wrong? 7:28
I'm 14 years old today and I'm gonna come back here 4 years later to learn something from college
OR, you could learn it right now so college feels like a breeze
@@santicruz4012 Good point.. but unfortunately, some things aren't ready yet 😒
what things?
U still young
Nigga enjoy life dont kill yourself from early

Thanks!
you may single handedly save my semester...pray up for my final
Not even a tutor, you’re the professor at this point
Properly explained! Really enjoyed it 😀
We could also make Saw-Horse Projections and just condense it's structure by joining the front and back Carbon atoms to get Newman's!
Just what I needed! I literally had a test tomorrow on this thing
you explain so much better than my garbage professor at USF!!! i love this so much, only you can help with orgo
Thank you from Korea. I love your explanations!
I think that he made a mistake at 6:20, it should be two (H) and not two (CH3) right ?
i was also lost right there
yes, that's just a mistake
Yeah mistake
Yeah, this
Perfect Timing😁
I understand very well 😊. Thank you so much ❤
Hi Thanks for the video. At 7:28 why the 4th conformation has 3 CH_3 in the back? Shouldn't it be 2 Hs and 1 CH_3 like the other projections?
yeah you are right . I guess it was amistake.
I think I'm not gonna flunk my O. chem test today, thanks!!
Thanks for this
Ur channel is underrated
Good luck on your exam in a few minutes🙏🏽
The best tutor long live ❤
thank you so much. this is really helpful!
Ok Mr. Do you have my course syllabus😂 we just did this yesterday
You always make things easy for me thank you mahn.
Never thought I would be back here after A level but here I am in university
Can I ask your major
Your explanation is top notch
Thank you
wait,wait,wait!!! You cant miss the maths and science tutorials,hurry and check it out student. thanks
thank you so much 🎉🎉🎉🎉
You're doing the most
Thanks for this fantastic explanation.
Appreciate you man, just wanted to let you know.
you're a legend
Thank you so much you really help me 😊
thank u sm ily i wish ur my teacher instead
what's the torsional strain value for ethyl and hydrogen tho? in 18:07?
Very impressive ❤️❤️❤️👍👍👍
Hi,
Any ideas for 18:12? My guess (without doing too much research yet) is that molecule 3 is the highest in energy relative to the other 2, given the numbers. Would you say that’s right, or do you suggest I do more research?
Thanks,

I agree, it has 17 kj/mol already besides ethyl hydrogen interaction
Thank you for these great explanations!!!
Hi I have a quick comment at6:42 minutes of the video at structure number 4 of Butane Newman you draw 14 hydrogen and 4 carbon is it for different molecule confirmation because I thought we draw a structure forc6H8. thanks I always benefit from your videos in science.
Yeah a human error 😅 thats fine. It should be only one CH3 (near the top CH3) and 2 atoms H there near the other two atoms
Thanks a lot for the video 🥰
what was the energy value of the ethyl hydrogen eclipse interaction?
🙌🙌🙌 THX brooo
in butene, how does the 4 structure exist 6:38 ? The other 2 hydrogen atoms are not drawn?
He made a mistake, I noticed it aswell

You sir are a marvel, thank you

Very clear explanation
Thank you very much
It's really very clear
My professor went over this ngl I left the class completely lost, I will watch this and lets see how it goes
very nice video
4th eclipsed butane conformation is wrong. For rear C, there is only 1 CH3 grp and other two are H . You wrote all 3 as CH3
It seems you're looking for error, rather than wanting to learn. E made a mistake, deal with it.
@@pauludom you are looking it from a different perspective. If anyone wants to learn properly he/she will have to study it correctly to understand.otherwise there will be a confusion. Think it that way.
@@pauludom yeah sure but he was saying true explanation but he accidentally wrote wrong
I got a D in ths class rn
can you please make an ACT math Playlist?
great video!
Hey, is the a newman projection for alkynes?
thank you sir
Also switched the methyl and ethyl around in the third conformation at 14:00. The hydrogen didn't move.
Oh i see. You're just flipping around the RS configurations willy nilly for the sake of examples.
ok mr.pickle lol
In Which class does your teacher or professor teach this topic in your nation???
In India, In competitive approach it's Highschool 1st year i.e. class 11th Topic.

11th only? for us it starts in 9th grade too! Im from cambodia.
Thx iam from iraq and ur videos is too good just need to explane more

Well well ❤
u are the man
God bless you soo much
Hi! Nice Video! Do you know if a gauche interaction between chloro and ethyl leads to a more unstable conformation than a gauche methyl-ethyl one?
Why can't we start at CH3, do we take into consideration 1, 2nd and 3rd carbon?
21:07 Why is comformation at the right corner more stable than the one at the left corner if they both have one gauche? How do I determine which one is the most stable of the two? I know that the most stable must be the one with the lowest potential energy but don't the two of them have the same potential energy? Or am I wrong? Do I have to do some steps to solve it? D:
i'm trying to figure out the same thing, and I can't figure it out!
I didn't get you, did he said that the right one is more stable than the left one? 20:58 he said, both the conformations are actually same with same potential energy, so you can choose either of them as they both are same but not the middle one
They are the same structure. Look closely! And he never said that one is more stable than the other. Listen closely!
You're really a god ...I love you
Can make a video on the Proper explanation of Gauss Law. I am having trouble understanding it
It's simple. All you have to know is this law is only applied in symmetry questions like cylinrcal or spherical symmetries. It's much easier than coulomb's law.
thank you!!!!
A student from Ohio State here. Wondering how I’m ever going to visualize these Newman projections on an exam 😅 wish me luck
could someone tell me the relationship between the potential energy and steady?
Remember this poem:-
If potential energy increases,
Stability always decreases.
@@gettothepoint2707 that’s not a poem and didn’t make it easier to remember lmao
i feel that is so saddening that i have to come to youtube to learn material thats gone over in class rather than actually learning the material in class
also thanks for making this video i am still going to fail my test tomorrow just maybe not as bad now
What a beast love you my guy
On the 2methyl butane
The methyl of the 2nd carbon, the 120 th degree posses the more stable
Isn't that right...
what is the energy value between a hydrogen and ethyl group? I can't find it anywhere
The values are in kj/mol
3.8/gauche = H-H
4 = CH-CH
6 = CH-CH3
11 = CH3-CH3
Finding the energy between those two groups depends on conformation (staggered or eclipsed).
In eclipsed formation the H and Ethyl group are aligned (so 0 degrees apart). This energy required needs to be measured but would typically be between 4-6kj/mol. It is higher than the H-CH3 eclipsed rxn which is 4kj/mol just due to the size of an ethyl group versus a methyl group.

Why is it near impossible to just determine only the finite number of low energy confirmations for complex molecules? And does the angle determine the energy level, or is the angle considered, but it’s matters where each atom is in Three-dimensional space?
how do you go from newman to line angle :[
By chance do you have videos on calculus 3?
I have a few. Not many at the moment.
