Definitions:

(2R,3R)-2,3-dibromobutane

A specific enantiomer of dibromobutane characterized by its stereochemistry, with both chiral centers having R configuration, used in stereochemical studies.

(2R,3S)-2,3-dibromobutane

A specific enantiomer of 2,3-dibromobutane characterized by a particular spatial arrangement of its atoms, as detailed by its R and S descriptors.

Chiral

Describes a molecule that cannot be superimposed on its mirror image, often leading to different chemical behaviors for each form.

Achiral

Describes a molecule that is superimposable on its mirror image, lacking chirality and, therefore, lacking enantiomers.
