Concept explainers
(a)
Interpretation:
The multiplicity and the chemical shifts for each shaded protons in the given compound are to be determined.
Concept introduction:
The chemical shift is defined as the difference in parts per million in the absorption spectrum of a particular proton from the absorption position of a reference proton. Tetramethylsilane is taken as the reference proton. Chemical shifts are measured in parts per million and it is dimensionless quantity.
