Definitions:

Enantiomer

Molecules that are mirror images of each other but cannot be overlaid onto each other, much like left and right hands.

Meso Compound

A type of stereochemical isomer with multiple stereocenters that is superimposable on its mirror image, making it achiral despite containing chiral centers.

Diastereomers

Isomers that have a different spatial orientation of atoms but are not mirror reflections of each other.

Meso Form

A stereoisomer with multiple stereocenters that is superimposable on its mirror image, thus being optically inactive.
