    Thanku so much sir. It is so easy to understand the concept of Poleriometer after watching your video. 😊

    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??????????????????????

    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 ?

      @@kamalsandhu650 Yes. If an achiral molecule has a net dipole moment then each molecule rotates PPL but another molecule cancels it.
