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.

Chiral Molecule
