Meso compounds cannot rotate plane-polarized light, because they have planes of symmetry, so they are "internally compensated." They cannot exist as nonsuperimposable mirror images of one another. Example: Tartaric acid, d, l, and meso.

Rotate Plane Polarized Light

False. Meso compound does not rotate plane-polarized light because it has a plane of symmetry which cuts the molecule in half making it superimposable on its mirror image. While one quiral center rotates to the left the other rotates to the right and cancels each other.
