i am too tired to sit on my desk because of severe depression. because of your videos (wich i can watch in bed) i´m still learning. you explain everything perfectly short and on point. thank you so much
hi sweetheart how are you feeling? depression is tough
@@enoughnonymity thanks for asking I'm smiling again bc i passed my exam :)
Whenever I'm depressed, I fail to do a single thing, idk, you're just incredible 😔❤️
hi, hope ur feeling better now. love
I hope you are feeling better now :) I am in the same boat, watching these videos from my bed. Tomorrow morning I have my organic chemistry final, yet I can't bring myself up to study for it properly. And i haven't seen my friends or anyone for days because I've been holed up in my room. Not even my roommates who literally live in the same house as me. I haven't even eaten anything in almost 30 hours but I can't get out of bed no matter how painful my migraine is or how hungry I am.
Depression really really really sucks. It deprives us of so much in our lives. I would never wish it upon anyone. I hope everyone dealing with depression finds a way out of that darkness. ❤
Where is "he knows a lot about science stuff! Professor Dave explains"??
I guess he just forgot to add it in aha
That intro is not used for vedios where he solves problems
@@shreyaskrishna6038 I was going to say that actually. that for his tutorials he puts that intro but for practices/tests etc.. he doesnt use it.
This is one of my pet peeves - drawing absolute stereochemistry when what is intended is relative stereochemistry. The straight bold/dashed bonds are a useful convention for what you want to draw, but simply writing (rac) or (+-) would also suffice. The question you have actually drawn is much harder to tackle because the solution necessarily involves a desymmetrisation, using e.g. a chiral Lewis acid in much the same way as a Jacobsen kinetic resolution but with CN.
Why's Chris Evans teaching me organic chemistry?
I found this channel while searching for Calculus and now I'm really interested in almost everything in it.
Loving these new organic challenges Dave!! You are amazing
We miss your intro and your awesome hair!!
That awesome hair🙂🙂✌✌✌
Brilliant video as always! I greatly appreciate your clear explanations. Super helpful!
Thank you very much, your organic chemistry videos have helped me a lot in building my basics and now i am able to solve even complex problems. Thank you very much🙂🙂🙂🙏🙏🙏🙏🙏🙏🙏🙏🙏
Thanks a lot for the organic chemistry practice it has helped me a lot!
Synthesis challenge? More like "Dave's the best there is!" Thanks again for so many wonderful videos.
I'm not taking Ochem anymore, just wanted to bring my PTSD back a bit
This asmr will help you fit back into society

I'm taking 2 in the fall. Trying not to get too comfortable.
@@ahmadrashid4853 gold
@@Purpose_Porpoise you're taking two ochem classes? Like lab and the lecture? if so ochem isn't bad, I got As in all my courses but it requires a LOT of practice. Try subscribing to Clutch Ochem, just google it, money's worth it
@@Ps3COD4Fan Sorry, I typed that incorrectly. I meant I'm taking ochem 2 in fall. Forgot to put the "ochem" part in my first comment. I might be taking ochem lab along w/ it, so you technically aren't wrong.
Easiest sub in a long time. Great work Dave! :D
Just one?? There should be more such questions like this. It's fun solving such questions.
i've got several more ready to go!
I think I'm in the wrong class.
Very nice explanation. Please make videos regarding stereochemistry and about asymmetric synthesis. It would help me a lot for asymmetric synthesis.
check my organic chemistry playlist
Thnkyu sir😊 expect more challenges frm organic synthesis.
If you're using CN- don't you have to actually use something like HCN? In that case, why would the H on the oxygen come from the solvent (polar protic?) instead of from the HCN?
Professor I study Mathematics but because of you I passed my time dilation physics test
For the first step can I use Br2,H2O to create a trans configuration?
Which sugar are not sweet on monosaccharide and disaccharide? Help tell me 🙏🏻😊
Clever mechanism, I initially thought to do halogenation of the double bond and then two sn2.
oh man me too, I havent watched the video yet, but reading your response it seems like i was wrong
Quinton Wilson I believe that if you halogenated the alkene with something like Br2 in a radical mechanism you would get a mix of stereoisomers.
Nice little review
love the synthesis practice problems!
Hey professor Dave,
I'm really interested in organic chemistry, can you please make a series explaining some basic reactions like this?
And please explain everything important to know, so it's easy to really understand.
Thanks so much
That's literally the first thing I ever did on the whole channel. Check my organic chemistry playlist.
@@ProfessorDaveExplains thanks
Why the nitrile doesn't reduced by NaH? And what reducing agent could reduce nitrile to amine?
Dave this is great, thank you
Dave, won‘t the introduction of the cyanide group result in a racemic mixture?
Hey Dave! love from India
Nice! But, isn't the deprotonation step through NaH not required because we never introduced a proton-source in the reaction?
it'll get protonated by solvent
2 dislikes from the frat earthers..
I mean flat earthers
Make that 3
Nice one! Say, is there a way to send you problems like this one (+solution of course) to be discussed here?
Loved this
nice i knew it, was thinking about it for one minute and i did know the answer :D
These are great!
Any plans for any future debates?
Don't look at this in a public place, a Karen will getyou arrested. No clue what this means though. I'm a simple mechanical engineer.
hey professor how do u know everything?Seriously?please reply
Enjoyed the video. This is being picky but wouldn't you just get a 50:50 yield of 2 diastereoisomers following the addition of the cyanide nucleophile? Would you possibly be able to do a video on how to plan a more stereoselective reaction?
Thank you 😁
You should do a video about the new largest star in the universe, Stephenson 2-18
*largest star known
I thought about using Br2, as that forms trans stereochemistry, and then I thought about reacting an alkoxide with the Br on the bottom after CN with the top? idk if that would work but it makes sense to me
Its very nice video
Oh! Oh! Umm, yes?
Hey Dave are u somehow associated with edurev exam app as they are using your videos
Hmm, no I'm not. That's alarming.
A much improved hair cut, easier to take you seriously now.
Q: Why is mCPBA putting the Epoxide on dashes and not wedges already?
You from
bro my dumbass made the alkyl halide I thought it all had to come from the starting material. Here's how I did it can anyone tell me if its correct? I used NBS in hv on the starting material, then I used LDA as a bulky base. Then I did O3 in SMe2. Then I took the three carbon product from that reaction and reduced with NaBH4 in ethanol. Then I used XS HBr. The I used 1 eq LDA. Can anyone tell me if this is correct?
Fi
Very informative, and handsome too ;)
Allyl bromide, not vinyl :)
Whoopsie
Hei Dave long time ago
I hope kent Hovind sees this lol
First comment
I guess you haven't even watched the video
that's basic JEE problem 💁♂💁♂🧘♂🧘♂
Didn't know ranbir kapoor is teaching chemistry.
thats not ranbir kapoor, hes a bollywood actor. This guy is from america
How do you take that oxygen on their in dashes?
And what is MCPBA?🤔 This haven't teach us in our class that's why I don't know about that.
Sir can you please make detailed video on this,I don't understand properly,if there you have added NaH then where it attack on the molecule?
sigh
I knew it. But i am german Dr. Chem.
what is your tattoo?
check out "ask professor dave #3"
Um, he asked what my tattoo is, and that video explains what my tattoo is. You're an enormous tool.
@@ProfessorDaveExplains ok thanks
@@user-le7ny8bq1l Have you actually debunked anything? Or is your handle just wishful "thinking?"
@@user-le7ny8bq1l I can honestly think of no nobler way to "get more money" than to dispense KNOWLEDGE. Spending one's time trying to "debunk" knowledge is a truly foolish endeavor.
I'm starting prof. Dave syndicate (A team that supports sir's channel to grow by sharing or etc (if we can't support on patron let's support in this way) :) ) let's make a discord channel or insta page to make sir more famous and share knowledge
