MCQ (Single Correct) +4 −1
a HyCHat Hy “HCH a 3 What is the stereochemical relationship between two above molecules ?
  • Stereochemical Comparison of Chiral Molecules:
  • When comparing both Fischer or Newman projections, sequential spatial rotation shows that all corresponding substituents ($-Cl, -CH_3, -H, -CH_2CH_3$) occupy identical three-dimensional configurations at both chiral centers with identical $(R/S)$ configurations.
  • Because non-superimposable mirror image relationship is absent and configurations are superimposable, the two structures are stereochemically identical (homomers).
  • Conclusion: The molecules are Identical (Option 4).

Correct option: (4) Identical
