Definitions:

Chiral

Describes a molecule that has a non-superimposable mirror image, often leading to molecules with distinct left-handed (S) and right-handed (R) configurations.

Achiral

Describing a molecule that is superimposable on its mirror image, indicating it has no handedness or enantiomers.

Enantiomers

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

Diastereomers

Stereoisomers that are not mirror images of each other and have different physical and chemical properties.
