Concept explainers
(a)
Interpretation: The order of increasing chemical shift for the given groups of protons is to be ranked.
Concept introduction: In NMR spectrum, peaks are known as resonances, lines or absorptions. On the horizontal axis, the position of absorption is generally referred to as chemical shift. The more the shielded proton less will be its chemical shift value and the corresponding signal will be produced at the right-hand side or lower frequency region. The more the deshielded or less shielded proton more will be its chemical shift value and the corresponding signal will be produced at the left-hand side or higher frequency region.
