Are d -erythrose and l -erythrose enantiomers or diastereomers?
Enantiomers
Erythrose has two stereogenic centres with no plane of symmetry and therefore, it has TheIUPAC names for d-erythrose and l-erythrose are: (2R,3R)-2,3,4-Trihydroxybutanal (D) and (2S,3S)-2,3,4-Trihydroxybutanal (L).
Therefore, they are the stereoisomers
