In this video, we look at how we can take carboxylic acids and transform them into acid anhydrides.

Feels like a friend just explained this to me. Thank you for explaining everything even the little things that other teachers assume we should know. Thanks man and great job
Thank you so much for ending half an hour's worth of MCAT confusion for me!
Thank YOU for watching :) so glad you found the video helpful! If you're looking for any supporting practice + answers (100% free) for these videos, make sure to check out the link in the description that goes to my website--same video, but the worksheets + solutions I've made are below joechem.io/videos/72!
Thanks so much, I was never getting this mechanism but you helped me out, God bless you sir
thank you so much for uploading all these videos!. they're so helpfull :)
@noablah, thank YOU for watching 😁. Make sure to check out my actual website joechem.io, because I have worksheets + guided solutions for each video (and they're free too).
Also, if you'd subscribe to my channel, I'd massively appreciate it!
Very clear explained well explained
The way you said ANOTHER function group is amazing !! 😂
this guy is great
I haven't got any answers to this: CAN I make acetic anhydride from 98,9 % glacial acetic acid with sulfuric acid catalyst? OR will it be Caro's acid?
And I like your videos. Very simple, good and informative. Greets from Finland!
Unfortunately in practice the direct dehydration of GAA to AA does not occur at all. People have tried using even P2O5 but to no avail. you can check out Internet Archive/bitchute for ChemPlayer's video on that.
There are a few practical ways to make AA, some easier than the other.
1. Classical reaction between acetyl chloride and GAA. But good luck finding acetyl chloride
2. Urea + GAA -> acetamide --P2O5--> acetonitrile --some magic voodoo--> AA
3. S + Br2 or Chlorine -> S2Br2/S2Cl2 + anhydrous sodium acetate -> AA
4. Acetone heated to 1000C -> ketene dissolves in GAA -> AA (ketene has toxicity roughly equal to HCN)
i loved it ...... thanks alot sir its really helpful keep it up😊😊😊
Great explanation thanks! Btw, your side view gives Ronaldo vibes
Good mechanism
Atiya, thank you so much--I'm glad you found the video helpful!
Make sure to checkout my website joechem.io for guided worksheets + practice, and if you know anyone taking Ochem please let them know about my RUclips channel/the website! Also subscribe for notifications cause I'll be publishing more content soon.
Thanks for the class! I learned a lot.
Could you answer a question please?
Are carboxylic anhydrides more or less reactive than carboxylic acids as adsorption sites for metals?
Thanks
Is this a reduction of the acid?
may I ask about acid anhydride. the question is whether acid anhydride can only be formed from 1 carboxylic acid compound together, if 2 carboxylic acid compounds cannot??
For example, mr. explained that only 1 compound was reacted
- ethanoic acid and ethanoic acid to give ethanoic anhydride
can ethanoic acid react with propionic acid to form acid anhydride?
that is all and thank you
Is it okay to write the protonation of the carboxylic acid and the attack by the other carboxylic acid in one step?
Hi, Youssef! In my experience, showing combined steps like that is absolutely valid, but it can sometimes be ‘ok’ or ‘not ok’ depending on the style of your instructor.
So as long as the arrows all result in valid steps, and your instructor is ok with you doing that, it should absolutely be ok 👍 (I also like to combine protonation and attack steps but when showing things I keep them separate for better illustration)
hmm I thought this procedure didn't work with acetic acid...
