This video walks you step-by-step through the acid catalyzed acetal formation reaction mechanism! You'll see special attention on the acetal, hemiacetals, ketals, and hemiketals in the mechanism as well as resonance so you see exactly WHY each step is taking place. You'll also see the pattern so you can apply this to more mechanisms!

Thank you so much for doing these simple yet comprehensive reviews. I’ve struggled with chemistry you have made the intricate pieces come together for me. So thank you! Sharing 💓⭐️💓⭐️
Thank you so much for your kind words, and you're very welcome!
Awesome , every step have cleared explanation by you, you are godess of chemistry
Thanks a lot 😊
I recommend you are the best,,in my physical classes i come out eith zero content
I'm sorry to hear that you're not learning much in class and so happy that my videos are helping make up for it. Thank you for recommending my videos
Thank you so much for this video.
I'm in 12th grade and I was looking for the mechanism of formation of acetal just for curiosity. Because there is a reaction of acetal in a chapter named aldehyde and ketone in our chemistry textbook. But there isn't any mechanism. So I was wondering if I could find a video about it. And there is only one and the best your video on UA-cam.When I heard you mentioning "professors may..." I quickly understood that there is something higher level chemistry going on here, but I still managed to understand every single thing and idk why I took every notes from the video. Hope this help me in future :)
You're welcome! I'm glad you found the video useful. To find my entire series on Acetals, make sure to visit Leah4sci.com/acetal
these videos are saving my grade, thank you so much!!
You're welcome! Glad the videos helped :)
Your teaching method amazes me. Excellent.
Glad to hear that!
You really made this topic obvious by emphasizing the 'why' great job and thank you.
Thank you so much for your kind words :)
Glad my professor referenced this to us to use that doesn't even show you what we're doing in the lab to teach us the things we actually need. But a good video non-the-less.
Glad you liked the video, but I'm confused about your comment.
After 8 min it was gold damn....mam you just made my day.... people like you inspire me to become a teacher in future....Thx love from India
My pleasure 😊 And follow your dreams!
Really great way of teaching maam , Thankyou :)
My pleasure 😊
i love the way you make the mechanism so simple, thank you so much!!!
Glad you found it simple and helpful
i could cry, had a horrible time at uni and you jsut explained it perfectly.. thank you so much is this the same when starting from ketone btw?
Oh wow, I'm sorry to hear that you had such a bad experience at uni. Glad this helped and yes, this is the same for an aldehyde and ketone
Nicely explained.. 😘
Thank you
Outstanding lecture mam .thank you
It's my pleasure!
@@Leah4sci u r welcome mam. Kindly give whatsapp number plz mam.
I usually like watching the Organic chemistry tutor for info dumps on o chem, but it honestly just occurred to me that he doesn't explain in very much detail WHY things happen the way they do. Whereas you highlight the WHY much more and it sticks in my brain longer because I know the WHY.
In other words, take my subscription.
Thanks so much for your kind words, and I'm so glad to help you find the WHY behind the method. And thanks for the subscription!
super helpful thank you for explaining each and every step beautifully !!! :D
you're so welcome. :)
In the TCAI cation intermediate why doesn't the aldehyde abstract the TCAI proton since its a stronger base due to sp2 hybridization?
I’m having a difficult time understanding which proton you’re talking about. There is no sp2 hybridized atom in the TCAI. The alcohol in solution chooses to abstract the most acidic proton of the TCAI, which happens to be the one bonded to the positively charged oxygen atom.
These videos are helping me a lot in my preparation for competitive exam ... Very much concept clearing
Glad to hear that!
MCAT?
Thank you SO much for this video!
You are so welcome!
I'm not gonna say the video is bad bc other people seem to be helped a lot, I think I'm just dumb.
Not dumb. You just don't know it yet. Orgo is TOUGH!
Easy to understand. Thank you!
You're welcome!
It was really a good video
Glad you like it!
Mam you have explained every concept very easily.😊
Glad to hear that!
Awesome video, so helpful!
So glad it helped!
Goood.
Thankyou so much
You're very welcome
It's helpful thank you
You're welcome
Please make a video on Grignard Reagent. Please
It's on my list of concepts to cover soon
Ohh.. thank you. 🙂
You rock, Leah!!! Seriously! You’re a gift from god!
Awww, thanks!
This video came just in time
Awesome! Glad to help
organic can be possible with leah
Awwww, thanks so much!
why is the alcohol the most negative in soln and not the h2o?
Could you clarify what you mean by “the most negative in solution”? At which point in the video do I mention this? A time stamp would be appreciated, thanks!
Nice explanation
Glad you like it!
Really a nyce explanations
Thank you so much 🙂
1:35 there no conjugation so how can resonance be there
Thanks for asking! Conjugation is not necessary for resonance to be there. For more on resonance structures in organic chemistry, check out my series at leah4sci.com/resonance
@@Leah4sci Ok
This will help alot
Glad I can help!
Thanks yaa
You're so welcome!
Thank you so much!
you're welcome
please trick for pi and sigma bonds on inorganic compounds
I'm sorry, but I'm not currently teaching inorganic chemistry
Mam here we add dry hcl gas
This reaction happens in solution. Therefore, we need an acid catalyst in the solution as well.
Needed it! Thanks!
You're very welcome! glad to help
Super understanding video, thanks for great video.
Glad the video helped! You're welcome! All the best!
mam you are a very good teacher of organic chemistry kep it up and please make a video for SN1 and SN2 reaction.
Thank you and I already have. Quite a few actually - check my channel
Leah4sci mam can you have any notes of SNI SN2 and
and E1 and E2 rex.
Just what's on my channel
thank youuuuuuu
You're welcome!
Nice
thanks
Awesome explanation!!!! Loved it!!!!! 👏✊👍
Yay!!!
But I think hcl gas is used which will not dissociate h+
No, HCl is used in this reaction as an aqueous solution. We must have that proton in solution in order to catalyze the acetal formation.
Mam i have doubts in organic chemistry
Can you clear it
And
This video is good for me
I'm sorry to hear orgo has you doubting yourself.

@@Leah4sci okk thank you so much for guide me
That was really good tbh
Thanks! :)
Reversible arrow use cases
Is this a question or a suggestion?
super please more
More acetals or more of something else?
thank you so much! so helpful
You're welcome! Glad to help :)
Well explained, keep going
Thank you 🙂
If I want my daughter to be a nurse does that mean she won't just because I want it?
It's a possibility ;) seriously, just show her the pros and cons and let her decide so that she can be happy in her own path. And no matter what, show her you are proud of her!
@@Leah4sci always!
Great
Thank you
Leah4sci God bless you....... keep on doing the awesome work ........ Regards
fucking love you, u the best
Thanks
i love you
Thanks so much!
