(a)
Interpretation:
Considering only the IUPAC names, the given pairs of molecules are to be identified as enantiomers, diastereomers, or neither.
Concept introduction:
A pair of configurational isomers can be identified as enantiomers or diastereomers on the basis of the R/S designation in the names of those molecules. If two stereoisomers have inverse configuration at each corresponding chiral center, they are enantiomers of each other. If two stereoisomers have inverse configuration at some, but not all corresponding chiral centers, they are diastereomers of each other.
