Which of the following can be measured/checked with the help of a polarimeter?
a)Optical activity b)Chirality of a compound c)existence of a racemic material

c
As we learnt
Polarimeter -
Rotation of plane polarised light is measured using polarimeter.
- wherein
A polarimeter measures the angle by which the plane polarized light is rotated.If a compound is chiral,it will show optical activity and rotate plane polarized light. A racemic mixture has zero optical activity.
