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!

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!

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! 2-8bit group

thanks I've been trying to figure this out all day :)

Thank you very much you're always saving my life!!

Thank you so much. You are a great teacher

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!!

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 ...👍☺️.

i just studied this at school and i wanted to learn more things so thanks bro

Made easy :) thank u

Thankyou very machiii!! you make organic chem easy..

perfectly explained, but please also write the formula for the enantiomere example

thank you for summarizing my two hour lecture

WOW! Thanks!!

this the smartest guy in the world

Great video sir!!!!

thank u so much dude.....

What a good explanation

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 :)

Well understood

Thank you Khan Academy

This is cool and all but how do scientists figure out the shape of all these molecules? Are they visible under special microscopes?

hello what about functional isomers for any type they are related

Are Enantiomers and "optical Isomers" the same thing?

@paoloferro2254

4 жыл бұрын

yes

Thnx

does they share the same chemical properties?

Just why would you dislike a video it showes you knowledge

Can you specifically define what the word superimposeble means.

What about optical and structural isomers?

salman khan my man!

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.

does enantiomers count for water images too??? if anyone knows the answer please respond...

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

i just finished chem and calc and psychology and never looked at my textbooks period

love you

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.
