Aromatic protons produce signals in the range of 7 - 8 ppm, due to the _________effect of $\pi$ electrons

Question

Quizplus · Accepted Answer

Aromatic protons experience a shielding effect due to the delocalization of pi electrons in the aromatic ring. This causes the electrons to circulate and create a magnetic field that opposes the applied magnetic field, leading to a downfield shift of the proton signals. This effect is called diamagnetic anisotropy, and it causes the proton signals to appear in the range of 7 - 8 ppm.  The other options (B, C, D, or E) are not relevant to the observed chemical shift of the protons in question.
