(a)
Interpretation: For a given set of molecules the number of signals expected in
Concept Introduction:
Homotopic: If the protons are interchangeable through rotational symmetry, then the protons are chemically equivalent and termed as homotopic.
Enantiotopic protons: If subjected protons in the molecule can be interchanged through rotational or reflection symmetry known as Enantiotopic protons and the protons are chemically equivalent.
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.
Replacement test: In the molecule; if replacing each one of the subjected protons with deuterium gives the two compounds are same; then the protons are chemically equivalent.
