Get exam-ready with my 12 OChem practice exams available only on Chemmunity: chemmunity.info/dave Join Chemmunity today to get access to 200+ instructional videos, practice problems, and more exams!
some of the stuff up there i consider to be second semester, like many of the synthetic techniques, but if you have specific request email it to me and i will try my best to oblige!
Sorry, but I really need to say that you are such a great explainer,! Even if I need to watch it possibly a few times to store the informations in my brain cells, it is explained so logically! Thanks
Pyridinium chlorochromate (PCC) is a yellow-orange salt with the formula [C5H5NH]+[CrO3Cl]−. It is a reagent in organic synthesis used primarily for oxidation of alcohols to form carbonyls. A variety of related compounds are known with similar reactivity. PCC offers the advantage of the selective oxidation of alcohols to aldehydes or ketones, whereas many other reagents are less selective.[1]
Me again! Would you consider making worksheets for your videos? They are literally a life saver, and that would be icing. Having the attention span of a squirrel (ADHD-inattentive), I can make it through these snippets. Thanks once again for making organic accessible to non-standardized (speedy, all over the place) students.
well to truly understand a reaction you must understand the mechanism, but they are all totally different, so you can just view things in a general way as oxidation or reduction by looking at how the number of bonds to oxygen changes for a particular atom.
Professor Dave Explains (This requires 1st a conversion into thioester?) Why wouldn't you always reduce to alcohol 1st, then use PCC to make the aldehyde?
+kevjtnbtmglr it may be that there are other functional groups you are trying to avoid tampering with. in synthesis, there is always the issue of trying to modify a particular functional group while leaving the rest of the molecule as it is. each molecule is a unique challenge.
+Ivana Mador-Bozinovic esters need a hard reducing agent to be reduced, LiAlH4 will do it, and you'll get the primary alcohol. ketones can be reduced by just about any reducing agent, even a soft one like NaBH4.

Thanks!
this is the BEST EXPLAINED video about organic redox on youtube. periodt.
This video just saved my life. Was about to drop kick all of my organic chemistry notes/books in the dumpster and give up lolll. THANK YOU!!
I wish i made money so i could give it to you
Ikr same here
Im in AWE. This video is absolute art. Thank you so much for explaining those intricate details that makes it all make perfect sense!
god tier explanations! I really hope you do 2nd semester organic videos after your biochem ones.
some of the stuff up there i consider to be second semester, like many of the synthetic techniques, but if you have specific request email it to me and i will try my best to oblige!
Top notch video, very clearly explained
Sorry, but I really need to say that you are such a great explainer,! Even if I need to watch it possibly a few times to store the informations in my brain cells, it is explained so logically! Thanks
Omg thank you so much am almost crying cuz I understood 😿😿
After searching for so long finally i found the most simple and cut tot he chase explanation thankyou so much professor.
Great explanation! Really helped me to understand that different agent gives different product :D
when a non-teacher, english speaker makes you understand better than your actual teacher lecturing in your mother tongue.
MERCI DE M'AVOIR FAIT COMPRENDRE LA CHIMIE ORGANIQUE
So clear and precise. Masterpiece
my guy really appreciate the effort prof love from egy
I'm still not doing great but this made sense! And I realize that I just don't understand the basics.
Thank you.
you save my life!!! tks, from Brazil.

Thanks so much! Ready to ace my Orgo 2 exam!
You're literally the best organic professor i've never met are you single?
Danielle Brennan he’s married
I just want an organic cutie, too. :-(
I Love You... 😭😭😭After your explanations I get things better. I am doing great with my assignments and hopefully great on my coming exam.
I need to LIKE all of your videos
Thanks Dave really helped in my exams
very helpful explanation, thanks so much

i have been tossing around the idea of pdf notes! i would have to charge a little something like a buck or so, but it could be a solid project.
Professor Dave Explains I would so pay a buck.. or really a few.
thanks for the amazing explanation.
Do you have the mechanisms for these reactions?
they're pretty easy to find, which one in particular?
Thank you ❤
Can you do a lesson about vacuum distillation, please?
+Dick Diver coming soon!
Hey Dave do we really have to memorize these reactions or si there a way to understand them logically without having to draw down the mechanisms?
well to truly understand a reaction you must understand the mechanism, but they are all totally different, so you can just view things in a general way as oxidation or reduction by looking at how the number of bonds to oxygen changes for a particular atom.
Omg, I understood everything! Thank you!
thank you so much
I totally agree with your explanation,but had a doubt,if oxidation meant to lose h2 molecule n reduction mean to gain h2 .
Can you do a lesson on synthesis?
+Carey Gann i will add it to the list!
He looks like ranbir kapoor
Even I thought the same😅
What about chromium trioxide (CrO3) H2SO4 ? Pls make videos about them too.. You're amazing :)
Why is alluminum less electronegative than boron?
Prof. Dave, what kind of oxidizing agent that can be used to remove NaCl from salty water?
just do distillation
top tier explanations!
Can you reduce carboxylic acids to aldehydes or ketones? How?
+kevjtnbtmglr fukuyama reduction

tyvm
what about reducing ester to 1°alcohol?
and reducing ketone to 2°alcohol? which reducing agents should we use?
+Ivana Mador-Bozinovic esters need a hard reducing agent to be reduced, LiAlH4 will do it, and you'll get the primary alcohol. ketones can be reduced by just about any reducing agent, even a soft one like NaBH4.
+Professor Dave Explains thanks a lot Professor :)
someone that had a quarrel with him in real life comes here to dislike his videos xD
Good
thanksss
ITS awesome
in ch3-co-oh reacting with nabh4 cant it even form ch3-co-h
nope! sodium borohydride is not strong enough to react with carboxylic acids.
thank you sir
god bless you!
I was served an ad for « zero water ». What a shame.
Damn
i understand nothing goodnight
