All the dislikes are from teachers who couldn't explain this as well as this guy.
funny how i paid $400 dollars for a textbook and $800 for a class that doesn't teach me jack, but you put it in a way where i can learn the topic in under 10 minutes for free... I LOVE THE INTERNET!
literally just thought the same thing.... Definitely spent more time watching Khan than reading my textbook
I've been having similar thoughts for quite some time. Makes me question the utility of university
I've been looking for something that can adequately explain this and finally here I am
Me too.I've been watching Khan academy since this year for physics and this really makes my topics clear.
$400 for a textbook???
I love his voice, it's like he loves teaching
Love Loyalty exactly
Ratio
Exactly dude
@@technicaltipstelugu8510 Dudette, to be precise

Your voice is calming. I was tense before I started watching your video, but I'm completely relaxed now.
I'm happy I understand english ... I'm Arabic and I study in French yet the only videos I find helpful are these !! It just shows how much important it is to learn languages!
Sal Khan, thank you once again for making chemistry comprehensible and relatable to me for the last 12 years.
I love this video. I clearly understood the concept. Thanks a zillion! This has got to be the best one out there on this topic!
I could not understand AP Bio textbook explanation but this video was so easy to understand.
Does this guy know everything?
Yes, indeed.
Yes
Yes
Yes, very much so
No
i love this guy and how he repeats every word/phrase twice or thrice, you're a hero
hey khan! thanks a lot for this video:) we are from eastern european country and we are future chemists. so our english teacher Natalia tries to help us with professional english vocabulary. all material was really interesting and useful besides that the theme was already well known for us.
we are sending u much love!

That last BIOLOGICALLY made me laugh hard!!!😂😂
at 6:43
Shaf Shafeen 🤣😂😂😂
Bia-bialollogy-biologically
Bahahahaha it slipped past me until I saw this comment
Am from India 🇮🇳 ...and the way you explain is totally like a magic ❤️ this topic very difficult before this video
And now cristal clear ... honestly thankyou so much sir ...👍☺️.
Awesome!! That's simple! Thanks a lot!!
you draw so neatly c:
thanks I've been trying to figure this out all day :)
Thank you very much you're always saving my life!!
I just keep liking! Thank you so much :)
Thank you so much. You are a great teacher
this the smartest guy in the world
It really helped me to understand the topic.
You are getting me through my degree, after watching an hour long lecture on this I did not understand however a 7 min video on here explains it all. Thank you!!
perfectly explained, but please also write the formula for the enantiomere example
i just studied this at school and i wanted to learn more things so thanks bro
did a better job than my college professor
thank you for summarizing my two hour lecture
Thankyou very machiii!! you make organic chem easy..
Made easy :) thank u
This is very nice his voice is convincing
This is absolutely freaking awesome. I'm just learning it to pick up a girl, but now I know everything I want to about isomers. Thanks :)
WOW! Thanks!!
Great video sir!!!!
thank u so much dude.....
man i love you
What a good explanation
I was never good at chemistry in high school but I somehow understood this at 27. 🤔
I'm a nursing student 1st year and this was so helpful thanks 🙏
Well understood
Thank you Khan Academy
The voice tells me to learn
Thank you ☺️ sir .....before your lecture I was unable to understand this things but by your teaching I am feeling good as a student...and I love your voice 💜
true
This is cool and all but how do scientists figure out the shape of all these molecules? Are they visible under special microscopes?
"World's Most Powerful Microscope- Lawrence Berkeley National Labs just turned on a $27 million electron microscope. Its ability to make images to a resolution of half the width of a hydrogen atom makes it the most powerful microscope in the world."
these are all theories i assume.
I have a chem final tommorow lol tysm Sal
good stuff!
thanku sir well explained
Excellent
thanks😊
I'm a humanities student in highschool but I takw biology. In biology, trans and cis fats can have the same chemical symbol but are structurally different.
Just why would you dislike a video it showes you knowledge
thank you, mwaaa ❤
Thank you
thanks !
Thanks a lot❤
thanks a lot
Now this is how things are simplified, I thought that I am about to learn only one thing but I learn 4, and one even put of my syllabus, 1000 times better than 40 to 60 minutes long time wasting lecture
All my teachers are perfect, am just here to revise
tyvm
Can you specifically define what the word superimposeble means.
What about optical and structural isomers?
i just finished chem and calc and psychology and never looked at my textbooks period
salman khan my man!
Thnx
All lovers 😍 of his voics like here
👇
hello what about functional isomers for any type they are related
does they share the same chemical properties?
3:16, Q-> how can a SINGLE bond allow rotation but a DOUBLE bond won't????
Are Enantiomers and "optical Isomers" the same thing?
yes
does enantiomers count for water images too???
if anyone knows the answer please respond...
How about constitutional isomers?
His voice reminds me of mark Jefferson from life is strange 😂 am I alone on this?
yes........yes you are
omg i hear it
dont mind that im 3 years late..
@@jkay5082 haha its okay, at least I'm not the only one
There are many types of chemical formula , molecular formula is one of them . it shows the number of atoms in a compound without displaying its structure such as: ch3h4 . isomers occupies the same molecular formula not the same chemical formula.
What is coal an allotrope or compound??
What are alpha, beta, gamma, delta isomers?
Same cardinality, different relation type
My god this was so helpful. Many thanks 🙏🏻
love you
Why do we need to know about the isomers?
He says why at the end
Chhun Kimly i
Cis-trans? Triggered!
please sal or someone, how to know if hetero or homolytic fission takes place
nvm i figured it out heres how i remember it
homo-you are born naturally like that- natural tendency to like - or +
hetero- you are induced
cos laws if this society is opposite of what logic dictates!
What about optical Isomers?
+isn't this topic teached in chemistry?
'optical isomers' are enantiomers (and maybe also cis isomers, I'm still learning)
@@KlasseCaldiny optical Isomers is a Chiraly Isomers that change the direction of light when light go through its solution.
But generally it's a stereoisomer.
And I'm still learning.
I have a Chem final in like 40 minutes
indian academy? nice video. makes science easier.
no, they're working in foreign country but the ceo is indian
@@sabiayy9298 No the CEO is Bengali.
Cis Trans means something....else nowadays
Hahaha (im trans and i think this is funny)
my chemistry teacher pronounces it as iiizzzz...
.ooommmeerrss
I'm a humanities student in highschool so I take History, Economics and Geography but I also take Biology as an extra subject. In biology, trans and cis fats are isomers.

Sir why the rotation of OH and H group in the 3rd carbon of glucose is different.. Please answer me
Who is watching this at 2024 ❓❔
Just us my guy
Me, like right now 😅
Asc
:)
5:12 i can just flip it and every thing well be fine
يلي جاي من نوطةpre x تفضلو لهون🤣🤣🤣🤣🤣
I wasted 50 pounds on a trash t.b lol
plz improve your way of presentation
But you don't have to say a word over and over as you write it... I can't complain too much because this is free though...
