Interpretation Introduction

Interpretation: The given red protons are whether homotopic, Enantiotopic or Diastereotopic to be predicted.

Concept Introduction:

Homotopic: If the protons are interchangeable through rotational symmetry, then the protons are chemically equivalent and termed as homotopic.

Enantiotopic:  If the protons are interchangeable through reflectional symmetry, then the protons are chemically equivalent and termed as Enantiotopic.

Diastereotopic: If the protons are not interchangeable through either of the symmetry operations, then the protons are Diastereotopic; the protons are not chemically equivalent if a chiral center present in the molecule.
