Organic Chemistry with Victor
США
Добавлен 26 июл 2019
Hi, I’m Victor from OrganicChemistryTutor.com, your Organic Chemistry Tutor!
I'm a professional chemist (yeah, I actually work in the lab), ex college chemistry instructor, and a professional chemistry tutor with over 20 years of teaching experience.
On this channel, I cover topics from college-level organic chemistry courses, ACS and MCAT exams, and advanced graduate-level material. I upload videos, posts, and shorts weekly, with occasional breaks during summer and holidays. I also try to answer as many questions in the comments as possible!
Let's get social!

Can you explain why the bulky group being equatorial makes the molecule more stable?
This is so far the best video I have seen on the mechanism of oxymercuration and demercuration reaction
Victor thanks a lot man You+leah+joe carried my whole ochem course fr and by the way how many of your viewers from india?
Ty
Yw
that trick is the answer to all my problems 😂
Ur the best organic turtor
My organic chemistry course ended around half a year ago, and I just wish I found this channel earlier, maybe than I would have done better
Is this a reaxn with ether ?
I am a student in Thailand. I am not very good at listening to English but I can understand the main points. You helped me understand NMR more. Thank you.
32:19 sir, can you please explain, here in the 2nd aromatic ring , doesn't the positions that you have marked as d and d are same ( doesn't it be represented by a single signal) it's really confusing
They are not the same for as long as groups X and Y are different. You might wanna watch theory tutorials before you go into practice 😉
Sweet
For the questions of this level, it’s reasonable to consider stereochemistry.
LOL tell me more 😂😂
I believe, there's an entire multi-season TV show dedicated to that 🤔
Isn't a similar reaction employed to synthesise napthalene ?
Yep
I thought protonation was going to occur at the OH in order to have H2O as leaving group. Please why is it not the case ?
I recently had a short about where to protonate acids and derivatives. Plus, I talk about it in several of my long forms videos.
Very cool
❤❤❤
Very nice but it would be cool to explain why N3 or CN are only nucleophilic, in other words the hard soft acid base theory and how it affects not only Sn2 reactions but conjugate and carbonyl additions, enolate chemistry etc.
I am planning to make a series of videos dedicated to the FMO and MO explanation of reactivity in organic chemistry. It will happen eventually, I promise 😆
Why is the sulfonation reaction not going to completion?
What does “catalytic amount” mean to you?
@VictortheOrganicChemistryTutor ohh I didn't get that
Tautomerism!!!! Your shorts are really making me sharper XD
That’s not tautomerism though, it’s a carbocation rearrangement. Those are not the same 😉
@@VictortheOrganicChemistryTutor but there is tautomerism that occurs here? Or am I completely missing something.
@@davidrosario8353 No, there's no tautomerism here at all.
@@VictortheOrganicChemistryTutor crap.
H-NMR? More like "Heroically good videos; you're a star!" 🌟 31:57 I was confused by that little guy 😆
Haha thanks!
Sweet
What a tutorial 😮 thanks God bless you bro🙏🥰🔥
Thanks!
That joke deserved a like cause wow corny😭😂😂
🤣🤣🤣
Is it attacking the less substituted side because of steric hindrance? And also I know the intermediate is rearranging for more stability but why is it unstable?
Generally, nucleophiles attack neutral epoxies from a less sub’d side. And since it’s a classic SN2 attack, sterics does play a big role there. It’s a 4-membered ring. It has a ton of strain even though P is “comfortable” with small angles, the other atoms are not.
Helpful video but in problem 3 wouldnt the H on the nitrogen have neighbours because of the CH2s?
NH and OH's don't split.
@@VictortheOrganicChemistryTutor Oh okay thank you so much! Your videos are incredibly helpful
Definitely mentally disturbed benzen
NOISE!
I prefer the fried egg benzene, which is just a circle inside a bigger circle 😂
sir, you have help me a lot! im preparing for my competitive test and i was struggling with drawing resonating structures, but this video has done wonders for me!! please continue the great work! thank you~
Glad I could help! Best of luck with your test!
That was clean
hehe noise!!!
Sni
If you mean SNi as in ipso-substitution, that’s not it.
You are my favorite orgo tutor. Youre the reason I have an A, thanks!
Wow, thanks!
Do more of these organic name reactoons. Very informative video
I have a very loooooong to-do list haha but I do have some of those name reactions on it.
Hello Victor, at 5:20 you drew a 3D structure with the P orbitals. What are those structures called, and how do we draw them??
It doesn't have any special name. I do have a dedicated video discussing the orbital drawings though.
can't we just show the machnism of second bromide ion attacking the carbocation? Why the need to give the first bromine the positive charge?
Because in a mechanism the steps are important. I had the same question but my professor said that experimental data showed that respective intermediates had been isolated or observed via spectroscopy and that's why these extra steps had to be included in the mechanism.
It shows the resonance stabilization of the carbocation. Otherwise, we don't have an explanation why it doesn't rearrange.
That's a bit of a stretch what your instructor is saying.
@@VictortheOrganicChemistryTutor not this particular question but for other similar issues this is the explanation I was given. You learn something new everyday XD!
Pretty awesome indeed! That feeling when you can actually predict what Victor is going to say... there are so many ingredients in organic chemistry that it's truly overwhelming at first but eventually something clicks, you start interiorizing the mechanism and everything makes sense.
Once you get a grasp of the fundamental principles and work a ton of examples so you start noticing those "tricks" yeah, you start looking at reactions in a very different way indeed!
Markovnikov’s law
I wouldn’t say a “law” it’s a rule at most 😂
Is there any reason to explain why hydride shift doesn't occur to form a more stable carbocation at the second step.
The first step doesn't really form a carbocation, we teach it this way out of tradition, I guess, the second carbocation is stabilized by the resonance from bromine.
you are very much appreciated my brother...👻
Always!
Benzylebromide or hexabromocyclohexane
Bromine hydroxyenol
I am a PhD candidate but I am still learning a lot of new ideas from your videos. Appreciated 🙏
Dude! I've been doing it for 20+ years and I still learn new stuff all the time! Not to mention that science in general is not sitting doing nothing. It's a never-ending story 😂
@VictortheOrganicChemistryTutor sir, you know the majority (almost all) of RUclips videos are general topic-based which have almost the same contents, but your videos are full of specific ideas and summarized, so that's why I said I am learning new ideas.
@@VictortheOrganicChemistryTutor Sir, I am in a country where I don't have access to English medium chemistry books. Could you please recommend stereochemistry book(s) which I can get from internet, Thank you
Very helpful. I'm taking chem online and doing labs at school. I watched the entire lecture and was completely lost, but now I'm getting it.
Stereochemistry is, in my experience, one of the hardest concepts to grasp as it requires a "3D mental muscle" which we just don't naturally have.
