Problem: The structures of four isomers of an aldotetrose are given below.Which of the structures are Diastereomers of A?a) Bb) Cc) D Enantiomers of C?a) Ab) Bc) D Stereoisomers of D?a) Ab) Bc) C 

FREE Expert Solution

For this problem, we have to determine which molecules are diastereomers, enantiomers and stereoisomers of A, C and D 

  • In this case, Fischer projections are already provided which means we just have to analyze the substituents (with -OH) specifically at C2 and C3 
  • Recall that enantiomers have the equal opposite of the substituents in Fischer projection. They are also mirror images of one another:
