QUESTION: At 15:24 You say the light is going through an enantiomer and the light rotates counterclockwise due to the field created by the dipole in the chiral molecule and then turn the molecule around so the front is the back and the back is now the front and the light goes through and is still turned counterclockwise. When the molecule is turned around from front to back would that not flip the field in the molecule and rotate the light clockwise. Why does the field stay the same rotating all the light counterclockwise when you turn the molecule around front to back?????????? If you flip the molecule i would think the field would be flipped too????????? So I understand how polarized light can shine through an enantiomer CRYSTAL and the light always be rotated in the same direction by the field the chiral molecule creates BUT if it is in solution then the molecules are in every which direction you can think of. Some are backwards and upside down. Wouldn't rotating the molecule in solution from front to back flip the torque force(rotating force/field) ????????????? I mean if I look down on a bottle of pop from the top of the bottle looking down on it I know I must turn the lid clockwise to close the bottle. But if I flip the bottle over and look up through the bottles bottom then I flip the rotation of the force needed to close the lid. Now it appears that lid is turning COUNTER clockwise relative to me. Wouldn't it be the same with flipping the molecule from front to back. Wouldn't that flip the force rotating the light in the opposite direction????????????????? How is the field that the chiral molecule creates not flipped when the molecule is flipped over. The field is part of the molecule. If you flip it then i would think the field would have to be flipped also??????????????????????
After watching such a wonderful video I have ONE question from Pakistan . Sir ! What actually is the "mechanism" that optically active solution rotate the plane of polarized light? I wish you answer my point. Thanks
that was brilliant stuff , i had problems understanding this chirals and all but u have done a great job and have solved my problem ... great animation as well👏👏
Sir methane molecule has zero net dipole moment does it rotate the polarised light when light passes through it ?? I know it is achiral but I am talking about only one molecule .
@@ProductReviewkk that's mean achiral molecule may rotate or may not rotate PPL but optical activity of the solution is zero of achiral substance and all organic compounds which have net zero dipole moment are achiral ?
Thanku so much sir. It is so easy to understand the concept of Poleriometer after watching your video. 😊
11:49 is what I was looking for. Thank you!
This is easily the best video out there on optical activity!

Thanks alot Sir!
U explained it vry clearly. U explained each nd evry thng.
I am a 11th grade student struggling to get the theory of optical activity of compounds. Awesome teaching Sir 😍.
Love from West Bengal ❤💚💙
It will help me in my physics practical a lot. Great effort and result in great video
Absolutely fantastic it made the concept so clear!!
Wow So this is it
Thanq this video was really helpful in getting concept clarity
Awesome video .👌👍👍👍
This is an Experimental Thing . But you Described it so well

Thank you sir
We dont need formulas and equation , we need imagination.
Everyone must have to see👍great
12:00 this is gold!
Loved the explanation!! ✨
Oh wow, I remember seeing this in 6th grade haha.. I was so confused but it was nice to be shown something that didnt feel condescending
Wonderful animation
That was Amazing!

Awesome ...getting a clear concept. Thanks for sharing this video.
Very nice, get lot of help to make clear concept on polarized light and basic of how polarimeter works.
Excellent ❤
Nicely detailed
that was brilliant stuff , i had problems understanding this chirals and all but u have done a great job and have solved my problem ... great animation as well👏👏
Informative and learning tutorial
It really has helped a lot . Thank you .
Amazing
Sir methane molecule has zero net dipole moment does it rotate the polarised light when light passes through it ?? I know it is achiral but I am talking about only one molecule .
kamal sandhu: No. Only a molecule with a net dipole moment will rotate PPL.
@@ProductReviewkk that's mean achiral molecule may rotate or may not rotate PPL but optical activity of the solution is zero of achiral substance and all organic compounds which have net zero dipole moment are achiral ?
@@kamalsandhu650 Yes. If an achiral molecule has a net dipole moment then each molecule rotates PPL but another molecule cancels it.
This video should have more views

Amazing content sir
Can I use this video for UA-cam .any copy right issue
Very helpful and well explained..thank you Sir
Excellent explanation...👌👌👌
Nyc video
Amazing very understandable explanation, thx.
Fabulous 👍🙏

After 11:48 pheel aa gayi ❤
Sir if there is bubble in soln then
Then the volume of the solution will not match based on the length of the tube which will result in the wrong reading.
Very nice
Amazing sir 💖
Good sir
Thank you sir......
You explained what I needed sir 💖 thank you sir ❤️
sir plz continue ur channel this vedio is after 7 month...
Rao Zikar Islam: yeah I will continue paying videos on this channel
thank you so much sir...
love & respect for u sir....
🙏🙏🙏🙏thanku sir!!!!!
Very helpful
