Chapter 14, Problem 3LGP

The ${}^{1}H$ NMR signals for the aromatic hydrogens of methyl p-hydroxybenzoate appear as two doublets at approximately 7.05 and 8.04 ppm $\left(\delta \right)$. Assign these two doublets to the respective hydrogens that produce each signal. Justify your assignments using arguments of relative electron density based on contributing resonance structures.
