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 nonoverlayable mirror images of one another, mostly molecules containing asymmetrical carbon atoms.

Identify each of the following pairs of Fischer projections as enantiomers or identical compounds: (Part a)

• If there is Chiral C in molecule then the mirror image of the molecule is note identical to each other but enantiomers
• No Chiral C so these mirror images are identical

Step 3:  b) Identify each of the following pairs of Fischer projections as enantiomers or identical compounds:

• If there is Chiral C in molecule then the mirror image of the molecule is note identical to each other but enantiomers
• (Chiral C is C which is attached to four different groups)
• Chiral C present so these mirror images are Enantiomers

c) Identify each of the following pairs of 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 each of the following pairs of Fischer projections as enantiomers or identical compounds:

• If there is Chiral C in molecule then the mirror image of the molecule is note identical to each other but enantiomers
• No Chiral C so these mirror images are identical
