(a)
Interpretation: For a given molecule the number of signals expected in
Concept Introduction:
Proton signals: In
Carbon signals: In
Factors affect the chemical shift values: The electronegative atoms which present nearer to the subjected protons withdraw electron density around the protons inductively makes the protons deshielded and shift the chemical shift value towards downfield.
