I can't believe I've been studying this for hours and not understanding, but it took you a few minutes to help me grasp the concept.... Thank you so much for your help ma'am 😍😍... God bless you 😍😍
Thank you so much Leah Fisch! As international student and English learner, I'm having a hard time in my organic chemistry class. However, your video helps me a lot. I have an exam in 3days and am ready to take my exam with a lot of confidence. Once again, thank you Leah Fisch. You also gain a new subscriber
You are amazing teacher. Its so simple.I could not understand this with my freaking teacher the whole year but now it took me just 5 minutes. 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/
Hey Leah, my prof emphasizes green chemistry, specifically switching out PCC with Dess-Martin or Fe(NO3)s, 4-OH-TEMPO, and Cr. for KMnO4 or Fe(No3)3 and TEMPO. It's impossible to find videos on it. Thoughts on a green chem switch in the future?
No ma'am , I was referring to reaction mechanisms of reactions such as Dehydration of alcohol, dehydrohalogenation of vicinal dihalide, Kolbe's synthesis ,etc.
That exact mechanism is not what this video addresses. For more on oxidation and reduction, as well as an overview of alkene and alkyne redox reactions, feel free to visit my site at Leah4sci.com/redox
***When oxidizing a primary alcohol using potassium premanganate (KMnO4-)****** My question is: does it become a carboxylic acid via the aldehyde hydrate or through the carboxylate? I cant seem to find anywhere that depicts the portion of the mechanism where the aldehyde transitions to carboxylic acid. What does it react with?? who attacks who?? What are the steps to this particular part of the mechanism?? Iv gotten as far as the aldehyde with no issue but im stuck on getting it to a carboxylic acid. Help please!

Actually, the PCC reagent is what 'plucks off' the hydrogen atoms and holds them in the end product. In other words, the CrO3 and pyridine will grab those hydrogens in a complex and concerted reaction mechanism. You eventually end with a by-product of H2CrO3.
Of course, but that is not the purpose of this particular video. You might benefit from the following video instead: leah4sci.com/alcohol-oxidation-mechanism Thanks for watching!

Hydride ions are reducing agents and so they will reduce aldehydes to alcohols. You'll need an oxidizing agent (with lots of oxygen) to oxidize an alcohol to an aldehyde and carboxylic acid
Thanks for even considering joining. I'd be honored to work with you in the study hall, but I understand that not everyone can afford it. That's why I offer so many free resources on my website: Leah4sci.com/Orgo
Im not even english but i understood better what u said in 7 mins than my chemistry teacher! Life saver!!
Woohoo! happy to help!
the first 2:29 minutes in your video explain much much more than the 10 video i’ve watched in order to understand the redox .... Bravo
Wow!! So glad I could help!
I can't believe I've been studying this for hours and not understanding, but it took you a few minutes to help me grasp the concept.... Thank you so much for your help ma'am 😍😍... God bless you 😍😍
You're so welcome!! Happy to hear my video has been useful.
I am a massive fan. You're videos have helped me immensely. Thank you so much!
You're very welcome, so happy to help you!
This was so well explained and illustrated Leah, thank you!
I'm glad you enjoyed it! You're welcome!
"PCC is a prude, and it doesn't go all the way." lol You're the best!
Haha! Thanks for watching!
You make it all soooo sinple ! I was always struggling before i found out about your channel
I could never thank you enough
You're so very welcome, happy to help!
Leah! you are amazing. I had 3 people try to explain this to me in class and I couldn't grasp it. Thank you
Glad I could help!

Good Luck on your test! :)
You're welcome, happy to help!
U r fundamentally very strong and teaching style is very effective...
Awesome
Glad you like it!
I feel soooo happy when I see that you've actually made a video before 😭😭
You're welcome!
You are amazing teacher. Its so simple.I could not understand this with my freaking teacher the whole year but now it took me just 5 minutes.
Thank you!!
The reason behind this might be your magical voice ..
LOL! Thank you for your kind words, but the reason is probably the way I teach
you are my best oxidation teacher
Thanks!
i just love your teaching way
any time
Thanks!
Wow, you made this concept easier, it's astounding, Thank You.🥰
You're very welcome
was struggling in class to understand this , thanks so much for the video !
oh! great to hear that! You're welcome! :)
you are gifted with a teaching talent omg you are amazing I am even a highschool student and I understand everything ❤️
Aww, thanks for your kind words! I'm so happy to hear that my video helped you understand!
Your videos are so helpful! Thanks for the great content.
You're so very welcome!
my teacher sucks so i didn't understand this when i was taught but now i do totally , thanks so much!!!
happy to help!
hy leah. joseph i enjoy ur lecture and am one of ur favorite subscribes made organic chemistry easy thanx :)
you're welcome!
Wow. Thanks! You've helped me to understand this topic.
Glad it was helpful!
This was extremely helpful. Thank you!!!
Glad it helped! You are very much welcome! :)
Very very nice ...explanation ...
Glad you liked it!
Thank u ....i was so lost on the aldehyde to the carboxylic acid
You're welcome.
Mam why excess Jones reagent quenched by IPA , not other solvents just like Methanol , ethanol etc

I'm not familiar with those
Amazing video
Glad you think so!
ma'am do you have any videos on preparation of alkenes??
Is this what you are referring to?
leah4sci.com/alkene-reactions/
No ma'am , I was referring to reaction mechanisms of reactions such as Dehydration of alcohol, dehydrohalogenation of vicinal dihalide, Kolbe's synthesis ,etc.
Mam i want to do something extra things.i want to do some advance synthesis through youtube channel.
Brief concept that u given was very helpful.

do you have like the full mechanism of oxidation and reduction of cyclohexene and cyclohexyne?
That exact mechanism is not what this video addresses. For more on oxidation and reduction, as well as an overview of alkene and alkyne redox reactions, feel free to visit my site at Leah4sci.com/redox

should we put H2 in the product? like the oxidation of alcohol is acetone or ketone + H2?
Actually, the PCC reagent is what 'plucks off' the hydrogen atoms and holds them in the end product. In other words, the CrO3 and pyridine will grab those hydrogens in a complex and concerted reaction mechanism. You eventually end with a by-product of H2CrO3.
@@Leah4sci i see so if there is no specific oxidizing agent the by-product is just H2?

thank you so much .from cyprus
You're welcome
thank you for this amazing video... nice work👍
You're so very welcome!
Can you also do a table representation of oxidation Tes
I am unsure of exactly what you're asking for, but you can find my redox cheat sheet and more at Leah4sci.com/redox
Can't there be any mechanism for oxidation reactions??
Of course, but that is not the purpose of this particular video. You might benefit from the following video instead: leah4sci.com/alcohol-oxidation-mechanism Thanks for watching!
Is there a way to oxidize the alcohol without chromium?

I think I love you...thank you so much for this video...absolute life saver!!
Yay, happy to help!
Wait I’m confused in the second and tertiary because in the drawing they both look the same
Wait I rewatched it’s the tertiary you said had a bugaboo (oh) and a methyl attached to it
Looks like you answered your own question! Thanks for watching. :)
totaly lved it .. thankyou
You're welcome!
Nice leature!!!
Thanks!
can you convert an alcohol to an aldehyde in presence of hydrogen ions?
H+ ions are reducing agents not oxidizing agent
Hydride ions are reducing agents and so they will reduce aldehydes to alcohols. You'll need an oxidizing agent (with lots of oxygen) to oxidize an alcohol to an aldehyde and carboxylic acid
How can you find out whether an alcohol has been oxcidiced or not?
Yes, there are specific experiments to test for alcohols vs aldehyde/ketone/carboxylic acid
NICE SUPER EXCELLENT MOTIVATED.
Thanks a lot!
perfect, thanks alot
You're very welcome!
Thanks your vedioe are so informative
Glad you enjoyed it
6:08 can hydrogen peroxide also be used?
I don't believe so. We usually see peroxide used as an initiator of a radical reaction, not as oxidizing agents in reactions like this.
@@Leah4sci Thank You ❤️
Very helpful 👍👍
