Alkene + KMnO4 Reaction
HTML-код
- Опубликовано: 3 янв 2025
- This organic chemistry video tutorial discusses the reaction between an alkene and KMnO4 with OH- under cold dilute conditions which produces 1,2 diols with syn stereochemistry. It also discusses the reaction of an alkene with OsO4 and NaHSO3 to form an osmate ester followed by a cis diol. It also mentions the oxidative cleavage of a cis diol with HIO4. Finally, it discusses the oxidative cleavage of alkenes using KMnO4 with H3O+ under warm acidic conditions to produce ketones, carboxylic acids, and CO2.

Thank you! I’m passing year 1 University chemistry because if you 🙌🏽
we have to study all this in high school. I'm so tired honestly I'm gonna fail chemistry this year gaahhhh
We study this in high school in india lol
@@abhaykhatavakar757
Hahah, that is honestly insane. You're a champ.
@aozla hayka what?! No way. In India, we study this at 16 years old😳😳😳
IITJEE. NEET Doubts forgot IIT, if you wanna get a decent college in India, you have to be expert in organic chemistry. They will ask the conversions involving multiple reactions
Thanks
I got my doubts clarified in the last 3 minutes of this video ;) ( 8:09 )
How come no-one ever shows the actual mechanism invloved for this reaction?
It's not fully understood and therefore, most professors don't require the mechanism for this reaction; however, because it's a commonly used reaction, they require you to know the product that is generated from a reaction with KMnO4.
Oxidation-Reduction reactions are very fast in nature which does not give us enough time to study the kinetics of the reaction and investigate its mechanism. We know the exact mechanism for very few oxidation reduction mechanisms.
I though it was only me who has this question
I have it . Do you want it ???
How I wish there was a repost button so I could repost this question. Because I was about asking..
Potassium permanganate? More like potassium perfect-manganate! This was a wonderful video, and I learned so much; thank you for sharing your knowledge!
very helpful for indians senior secondary students and jee aspirants.
Jee ka prep kaisa ja raha he?
@@sandeep7973 acha chal rha h
Rishi Raj physics ke liye koi ache RUclipsrs suggest kar sakta he kya? Physics wallah ke alawa
@@sandeep7973 physics wallah, concept acche se clear kr sakte hai
Rishi Raj uske alawa? Kyuki uske videos bohot lambe he
This guy teaches way better than my school teacher.
Currently in 11th grade studying for JEE, and it makes me realize how difficult our course is as almost all my resources are university courses
Perfect video! Thanks for explaining the stereochemistry along the way.
Hey peyton
IIT JEE students , where you at ? ;)
Where you are buddy?
Thank you so much i didn't know about the acidic conditions
Sitting paying attention drawing everything and then
2:44
4:00
BOOM OH from KMNO4
It's not OH from KMnO4 dummy
ਸੁਚਾਰੂ ਢੰਗ ਨਾਲ ਸਮਝਾਇਆ
Wow so exceedingly clear and helpful. Thank you!
Great.. Thanks Prof. from my deep heart..
THE ORGANIC CHEMISTRY TUTOR🤛
What if the reaction is to be held in acid conditions .??! (reaction of alkene with KMnO4 under {H+})
He starts talking about acidic conditions at 8:15. H3O+ is the same as H+ =)
Thks it helped me in jee
U cleared jee mains jan ? How was the paper in jan
Can you do examples with benzene substituents please? I understood everything in this video but the moment you add a substituent, I have a meltdown and panic attack followed by a straight-up girl fit
A bit late but in those cases I believe KMnO4 reacts like an oxidizer and grab’s electrons
At 7:35 shouldn't the methyl group be oxidized to carboxylic acid too. Or does it only happen in benzene only.
Only carbons with the pie bond will be oxidised, just remember this because chem was never really my main subject.
Happens with benzene derivates only (side chain oxidation)
Thank u so much. Your videos r very helpful and easy to understand
sir so can we say , conc kmno4 behaves like oxidative ozonolysis reaction under acidic medium ?
My fav tutooorrrr
Thank u so much.. it helped a lot
where can i find reaction with OsO4
It is shown
hi sir, i dont think one can consider a mirror plane as shown in the beginning of the video as cyclohexane exists in chair form and not planar form. cis 1,2 dihydroxy cyclohexane is disymmetric and hence chiral . However it exists as a non resolvable d-l pair since both isomers exists in an 1:1 enantiomeric excess . so it doesnt show a net optical activity ..
I owe you a lot🙌
2-methyl-2-butene in KMnO4,OH- cold will be what
What about under neutral conditions?
Thank fuck for the mechanism cause I was close to a mental breakdown
What about oxidation of Alcohol in Neutral Medium
Aldehyde forms
Does potassium permangenat react with ether?
So how will you draw the seperated structure?
You explained so well as explained by MIT prof. Because I have passed through MIT and I am an software developer
Your English sucks
How did you excel at that SAT with English this horrible?
Really, bro I don't think so
Ha ha
I see we have the nice people of the RUclips Comment section here
Guys he must be talking about Manipal
How KMnO4 goes to MnO2, in my reaction it is going to MnO3H
Precise points gvn..
THANK YOU VERY VERY VERY MUCH
شكراً جزيلاً
Oliver Road
Thank you
What is difference between product of acetylene kmno4 and normal kmno4
does anyone have an arrow push link for the last problem
