You made me understand what I struggled with for weeks during my lectures, in only 12 minutes.
Thank you
Wow, that's awesome! So glad it helped clear things up for you!
This video made so much sense. Everything that made no sense in lecture you explained in 12 minutes. You're the best, Leah!!! Thank you!
I'm so happy I helped you understand, that's always my goal!
@@Leah4sci❤
Thank you so so much, I had no idea what was happening in my Organic classes
I'm glad I could help
You're a life saver thank you so much!!
Happy to help!
Your's way of teaching organic chemistry is awesome thanks a lot a mam
aww... thank you for the kind words
thank you leah i have been watching your videos since 0rgo one you are really an amazing organic teacher
Glad I could help!
First time understood what acetal and ketal is
I'm so happy to hear this! Thanks for watching.
This is the best instructional video of all time
Yay! So glad you like it!
Thank u so much, Ms. Leah. You've been helping me a lot.
I'm so glad!
For organic chemistry I directly search your videos..!!
Awesome!!!! Thanks for that!
Best video to quickly revise at 1.25, thank you 🙏
Glad it was helpful!
Always appreciated for free education, god bless you
You are very welcome!
Thank you I was very confused and u made my concept clear and you told exactly the point I were searching for
You're welcome! Glad to hear it!
11:05 Gas mask analogy. Instantly goes from short term memory to hippocampus storage within 5 seconds. Thank you!
WOOHOO! You're welcome!
I am glad all your videos exist !!
I'm glad they do, too!
I feel like sending you a box of chocolates because you helped me so much to understand this chapter. I having struggle with it for a full week until I found this video. I totally get it now. Thank you so so much.
Yum! I love chocolate :) I'm glad I was able to help!
Thanks for the video it’s really help me in my organic 1 class
Glad to hear that!
Yes keep uploading new videos for us I really appreciate it. I’m watching from The Gambia 🇬🇲 it’s in west Africa.
Thank you!!! I have been waiting for this for so long!!!!
You are very welcome!!
Thank you Bhat!
what would the result be if a base was used? (i got asked this question)
Thank you so much! I was having trouble with this, but everything makes perfect sense now!
Great to hear it helped you!!
great video. I always felt intimidated any time i heard acetal or ketal. This video breaks it down very simply! THANKS!
Always happy to help! You're so welcome.
@@Leah4sci Do you do MCAT tutoring?
Thank you so much for an easy visual breakdown! :)
You're very welcome!
I always forget this and have to look it up around this part of the quarter. Thanks.
You're welcome!
Thank you so much mam ! But mam, in my textbook it is written that ketones do not react with monohydric alcohols at all, and no such reaction is given. It is written that ketones react with dihydric alcohols to form cyclic ketals , and noncyclic ketals are unstable. I am still a high school student and so I do not know much about acetals and ketals.
What I think is, as cyclic ketals are stable the reaction proceeds towards right and we can isolate the product, but in case of non cyclic ketals, as they are unstable the reaction proceeds towards the reactants and we cannot isolate the product.
This is all my prediction, if I am wrong then please forgive me and clarify me.
Thank you .
I'm sorry, but I don't offer tutoring over social media. For help with questions like this and more, I recommend joining the organic chemistry study hall. Details: leah4sci.com/join or contact me through my website leah4sci.com/contact/
@@Leah4sci Oh, I am glad that atleast you replied and offered to help me mam. Thank you !
this makes way more sense than in class.
I'm sorry to hear that your professor didn't do a good job explaining this, but so glad that my video was able to clarify that for you
Wow.your technics are amazing.thank you so much.
You are so welcome!
Thanks for taking effort to make this vedios and making it very simple
You're very welcome!
Thank you!!!
You're welcome!
Thank you. Short and sweet. Very helpful review.
You're very welcome, glad you found it helpful.
could you pls make a video on transacetalization or the cascade reaction? I'm in Orgo 2 right now and we are getting into that. Unfortunately there isn't much material online regarding those processes
Thanks for the recommendation. I post free videos as I have time and am always looking for suggestions.
I'm very glad I found your channel!!!!:) Thank you mam for your amazing videos.
You're welcome!
Awesome, kind of makes me want to go back to college to take a little more Ochem.
you don't have to be in college to learn. I'm learning so much since finishing schools ages ago. The learning never stops. Glad you enjoyed the video
Hi Lea , thank you so much for your great work, I want to know are there any videos related to protecting groups in your channel to study ? or is there a way that you could advise me to study them?
I cover the Cyclic Acetal protecting group in the last video of my Acetal Series at Leah4sci.com/acetal

This is the best ever ! Acetals made easy!
Thanks for the feedback! :)
Nice way of point to point study.. Thnku mam
You're welcome! Glad to help! :)
Thank you for the videos...they are super ¡¡¡ I have a question....why when methylating glucose for example, there is only the annomeric C which takes the CH3 and not the other OH around the other carbons of the molecule??? Thanks a lot ¡¡¡
I'm sorry, but I don't offer tutoring through UA-cam comments. For help with this and more, I recommend joining the organic chemistry study hall. Full details: leah4sci.com/join
Asalm o alaikum...ma'm thanks for this video ...and plz make video on regeoselective and regeospecific comparison .may u live log...
That's a good idea for a video. Maybe down the line
Leah4sci thanks ma'm
She is amazing !!!
Awww thanks!
Thank you , it helped a lot
You're welcome, glad it helped!
You are my hero
AWWWWWW
Gracias, me ha servido de mucho
You're welcome!
can we not use a geminal diol to protect the carbonyl?
Thanks for watching and for the question. The standard is to use a vicinal diol as a protecting group. Using a geminal diol (where the two hydroxy groups are bound to the same carbon) causes a bit more ring strain than is desirable.
I read that ketone do not react with monohydric alcohol.. Is it true.. Clear my doubt
I'm sorry, but I don't offer tutoring over youtube comments. For help with this and more, I recommend joining the orgo study hall. Full details: leah4sci.com/join
Awesome!
Thanks!
You are the best
Aww thanks!
Thank you
God bless you
You're welcome! Glad to help! :)
You’re my savior
awwww! glad to help! :)
hellow dr.
how can i know,l solve by protect or not?
We use a protecting group if we want to perform a reaction without affecting a highly reactive group on the molecule. It is useful in synthesis when we want to react a molecule that has multiple functional groups with selectivity.
love you!!
Thanks!
this helped me a lot
Glad it helped! You're welcome :)
Your express is so good. 143
Glad you like it!
Thankkkkyouuuuu
You are very welcome!
U r amazing
Thanks!
Love it
Glad you enjoyed it!
God bless u 👍
Thank you!
Plz, make videos for addition of cyanide ion to aldehyde and ketones
I'm currently working on other topics right now, but I will consider your suggestion for future videos :)
Pls ur writing is covering de eqns making it hard to understand
Thanks for the feedback, I appreciate it
best :)
thanks!
I love Chemistry... I want to teach chemistry for iitjee
You're very welcome
Leah. I like your videos a lot, but what I like the most, are the ridiculous comparisons. 11:04 that sentence ended me
Glad you liked it! Anything that helps it stick!
