Answer: Enantiomers 31. a. Comparing two molecules: The Same: all centers match (R versus S, or by alignment of the Fischer Projection) Enantiomers: all centers are completely the opposite (R versus Sor by not being able to completely align the Fischer Projection) Diastereomers: some centers completely match while other centers do not.
