Concept explainers
(a)
Interpretation: The indicated proton in the given pair of compounds that absorbs farther downfield is to be identified.
Concept introduction: Depending upon the electron density or the concentration of electron around hydrogen atoms, the chemical shift values of proton varies relative to the reference signal. The terms, upfield and downfield expresses the relative location of signals. The meaning of upfield is to the right and of downfield is to the left.
