Question

what is optical activity in physical chemistry

Answer 1

Optical activity is the ability of a chiral molecule to rotate the plane of plane-polairsed light, measured using a polarimeter.

hope this helps you out!

Answer 2

${}\huge{\bold{\red{heya......}}}$
↔Optical activity describes the phenomenon by which chiral molecules are observed to rotate polarized light in either a clockwise or counterclockwise direction. This rotation is a result of the properties inherent in the interaction between light and the individualmolecules through which it passes.
