Meso compounds in organic chemistry represent a specific stereochemical class wherein molecules possessing multiple chiral centers exhibit internal symmetry (typically a plane or line), resulting in overall achirality and optical inactivity despite the presence of stereocenters. The governing principle establishes that such compounds are superimposable on their mirror images due to this compensatory symmetry, rendering them optically inactive as they do not rotate plane-polarized light. This concept delineates a boundary condition within chiral chemistry where local chirality does not dictate global optical activity, distinguishing meso forms from both pure enantiomers and simple racemic mixtures based on structural criteria rather than just stereocenter count.
