Question

The interchange of two groups (Br and C H subscript 3 end subscript) at the chiral centre of the projection formula (I) yields the formula (II), while the interchange of another set of two groups (C subscript 2 end subscript H subscript 5 end subscript and Cl) of (I) yields the projection formula (III).

Which of the following statements is not correct about the structures (I), (II) and (III) -

  1. (II) and (III) are identical    
  2. (I) and (III) are enantiomers    
  3. (II) and (III) are enantiomers    
  4. (I) and (II) are enantiomers    

The correct answer is: (II) and (III) are enantiomers
