Definitions:

Optical Activity

The ability of a substance to rotate the plane of polarization of polarized light, a property observed in chiral molecules.

Superimposable

Describes when two objects can be placed on top of each other, matching perfectly in shape and size.

Meso Form

A type of stereoisomer with multiple chiral centers that is superimposable on its mirror image due to a plane of symmetry, rendering it achiral.

Chirality Centers

Specific atoms within a molecule that have four different groups attached, resulting in non-superimposable mirror images.
