The signal which represents the greatest number of protons in the given NMR spectrum is to be identified. The signal which represents the fewest number of protons is to be identified. Roughly, the number of times more protons contribute to the former signal than to the latter is to be determined. Concept introduction: The integral trace for a single peak resembles a stair step and the height of that stair step is proportional to the total area under the peak. The higher an integral trace’s stair step rises for a particular signal, the greater is the number of protons that contribute to that signal. The number of protons that generate that peak is proportional to the area under an absorption peak. A proton signal is represented by the orange peak. The blue stair-step line is the integral trace, which represents the cumulative area under the peak (represented by the shading) going from left to right.
