Question

Identify each of the following pairs of Fischer projections as enantiomers or identical compounds: (13.2,13.3)

Short answer

Part (a) :

Part (b)

Part (c)

Part (d)

Step-by-step solution

Introduction (Part a)

• Enantiomers are chemical isomers that are non-superimposable mirror images of each other.
• Therefore, two enantiomers of a chemical compound will have the same chemical bonds but completely opposite three-dimensional structures.
• It is important to note that enantiomers are isomers that are not exactly the same as each other, and they cannot be superimposed on each other.
• Moreover, these types of stereoisomers can be considered as mirror images of each other.

Identify the Fischer projections as enantiomers or identical compounds (Part a)

• If a molecule contains Chiral C, the mirror image is not identical to each other, but enantiomers are (Chiral C is C which is attached to four different groups)

  These mirror images are Enantiomers since Chiral C is present.

b Identify the Fischer projections as enantiomers or identical compounds 

• If a molecule contains Chiral C, the mirror image is not identical to each other, but enantiomers are (Chiral C is C which is attached to four different groups)

  These mirror images are Enantiomers since Chiral C is present.

Step 4:  c. Identify the Fischer projections as enantiomers or identical compounds 

• If a molecule contains Chiral C, the mirror image is not identical to each other, but enantiomers are (Chiral C is C which is attached to four different groups)
• These mirror images are Enantiomers since Chiral C is present.

d  Identify the Fischer projections as enantiomers or identical compounds 

• If a molecule contains Chiral C, the mirror image is not identical to each other, but enantiomers are (Chiral C is C which is attached to four different groups)
• These mirror images are Enantiomers since Chiral C is present.
