Concept explainers
(a)
Interpretation:
Whether D-erythrose and L-erythrose are enantiomers or diastereomers has to be stated.
Concept Introduction:
Enantiomers are the compounds with same chemical formula but differ in configuration of the chiral center. These are known as optical isomers. Enantiomers are basically stereo-isomers of the same compound. Two compounds are called enantiomers of each other if they are a non-superimposable mirror images of each other.
Diastereomers are also the compounds with the same chemical formula. These are also a type of stereo-isomers. Two compounds are called diastereomers of each other if both the compounds have different configuration at the one or more (not all) equivalent stereo centers. These are not mirror images of each other.
