Chiral = optically active Achiral = optically inactive

Except in meso compounds where you can have chiral centers but then the molecule is achiral, therefore optically inactive

Unbelievable how you turned the topic to so easily understandable!! Thank you so much

worst concept best exemplified

I say wow 😮...wow huge respect...u nailed it......I understood very nicely

I have a pretest today, and thanks to this amazing video, with amazing explanation from the amazing Khan Academy! 😆😆😆

Perfect..!! Thank you

you guys are amazing! thank you soooo much!! this video saved me.

Thank you very much! Finally I know how plane polarized light works! My teacher kept talking about angling wavelengths but he never showed me an apparatus diagram to relate this to.

YOU ARE A LIFE SAVER BROO.. CANT THANK YOU ENOUGH

amazinnnng ...thx

U r amazing. I understand finally this concept .

what u want is at 8:50

Helped alot in understanding optical isomerism. Thx!

As always, a perfect explanation

Great explanation 👏😍 thanks 🌹

Wow...cool! Thanks!

well explained! thank you

This is actually really cool

Awesome video, thanks prof :D

Thanks a lot

OMG. IS THIS WHAT MY PROFESSOR SPENT 20 MIN TELLING I COULD NOT GET IT. THANK YOU

You write very nice

thanks

To understand why this works, look for the KZread on optical rotation by Steve Mould. You will thank me.

what if the optical rotation of a given mixture is 0 degrees? does it not possess a chiral center then?

@ouss991

it could be 50% dextro 50% levo then the rotatory power cancels out and the optical rotation = 0

Sir which are the optically active compounds??? Can you please give some examples?????

how do we know if plane is rotated clockwise or anticlockwise

ahamed akmal last thing he said in video, it is determined experimentally, so nothing can you say by looking at the structure and nothing can you do in your mind to make get this experimental data other than do it in physical world in the lab.

In the tube is there only one enantiomer at a time ?

I have a question why can not compounds that do not have optical isomers rotate a plane of polarized light ? You mention that the plane of polarized light will be rotated because of hitting molecules why doesn't it happen with the other compounds ? Thank you in advance

my reference is mcmurry's book foundations of organic chemistry, this polarimeter was mentioned but it was Jean Baptiste-Biot's work and not pasteur's? please enlighten us. thank you.

Angelica Martino optical activity was discovered by biot. But Pasture who could discover dextro laevo and racemic mixtures for tartaric acid and even could separate the isomers.

love you from i have exam tomorrow xD

You haven't mention if enantiomer is there. and talked about the enantiomeric excess

Wow, do you use Organic Chemistry Book by Klein? Thanks for explaining it :)_

I'm a foreign student and i have a question forexample, if there's a compound (+)-binaphthol, how do i pronounce (+)? Plus? Or positive? Is plus a wrong way to call it?

@ammararajapurkar2531

7 жыл бұрын

김다미 You can pronouce it as d-binaphthol (i.e.dextro binaphthol) & if it is with a negative sign then it is denoted with "I"sign, written as I-binaphthol ( for laevo binaphthol) In other words, d is for dextro(+) & I is for laevo(-)
