this man is a genius and one of the best teachers alive. I used to watch your calculus videos, and am very surprised to see you teaching organic chemistry as well. Is there anything you don't know how to do?
I am a BS Chemistry student and I have an organic chem teacher who is a Ph.D degree holder, and yet, everytime she teaches the lesson I can't hardly keep up. She doesn't know how to make the lesson easy for us to understand. That's why I'm glad I found this channel and I can get along no and understand clearly our lesson. Thank you! :)
Your videos are amazing! I have so much more confidence in chemistry now due to your videos! I actually think I will pass my first year of Pharmacy! THANK-YOU!
Just so you know, when you arrow push you are moving a pair of electrons not a single one. So upon formation of the alcohol the resulting water molecule would have two lone pairs and not a lone pair and a free radical. Not going to happen!
Your use of curly arrows is *wrong!* Their correct use in chemistry for reaction mechanisms is defined to shift two electrons (one bond or one lone pair), not one. If you wanna shift one electron, you should have used a half-arrow, but this would be incorrect in your case too, because you're not describing reaction with radicals, but normal reactions.
he made a video clarifying this. He uses this notation because it makes more sense as to what s happening really since the whole pair isn't donated, its just 1 electron
Some work is worth more than money alone. Besides if you look at all the financial stuff up on his site I think it is safe to presume that he has done ok ;).

He does everything

Same to you .
Get good noob
Thank god for this. I'm so thankful when I open a Khanacademy video and it's Sal speaking and not one of the other people. Best teacher there is.
Same thing with my professor. Often times, more than half of the class has trouble keeping up! Thank you Khan Academy!
Your videos are amazing! I have so much more confidence in chemistry now due to your videos! I actually think I will pass my first year of Pharmacy! THANK-YOU!
Thank you so much! Because of you I have confidence that I will pass my Gamsat exam this Saturday!
Sal! Always with concept clearing videos!
Mr. Khan could you post a video teaching how to absorb and understand that big amount of knowledge and how you can you get it???

Instant like and abo- This channel rocks!
Sir .. thank you so much .. this was very helpful..!
Khan Academy rocks again and again !!
i was lost.. glad i found you to show me the way.
Thanks Mr. Sal , now that you have taught the real mechanism , it would be a piece of cake to understand the rest !
this video is 10yo???? omg the quality is brilliant
This is acid-catalyzed tautomerization, right? Thanks for the explanation!
YOU ARE AWESOME
I hope youtube pays you for this Mr. Khan :)
Paul Alava he is Salman Khan!!
literally 25% of india is salman khan
sabrina zia what do you mean?
The day this man teaches Chinese will be the day I will name my first son "Salman".
شكرا جزيلاً
thank you so much
Is tautomerism able between -COOH?

good

Lol -0.5 marks I remember RIP
....amazing...........very nice vedio ............thankyou sir ...........
khan i freakin love you man, please come and teach in my unvi :P
well made! thumbs up
Would the enol tautomere be more likely in another ph than neutral or physiological pH?
Very good

U did better than my professor
Khanacademy
great
Wow
I love you Sal
good
I always watch your videos :) It saves me from my horrible professor that doesn't teach what he tests...seriously

@bowmowbow and physics and general chemistry
F*****g amazing dod. Love you.
why isn't it possible that the water molecule attacks the carbonyl carbon and then gets deprotonated so it becomes an alkane with two hydroxy groups?
it can't since carbonyl is most stable
+takash gon It can actually, but it would just immediately convert back to the carbonyl since the C=O bond is much more stable
I think you have the beta carbon labeled as an alpha carbon.
It took you 8 minutes to explain this when my lecturer took about an hour.
my lecturer took 2 hrs!!!!!!!!!!!!!!!!!
khan academy is amazing
freelanceteach >>>>> Khan.
I hate chemistry so much!!!
Floyd Collins Then you must hate yourself too, since your entire body is made of chemistry.
+Bon Bon 😂😂😂😂😂
that's the dumbest statement i've ever heard.
I know
I love Chemistry so much !!!!!
@walkerahl thats not politically correct
wuold be a good video if the guy knew how to use curly arrows...
I don’t get anything. God.
why do you call the compound a guy?? it's really funny and how did you know it's a guy why not a lady?
lol

Chemistry is aweful
