In the ¹H-NMR spectrum of pyridine, the chemical shift values are influenced by the electron-withdrawing effect of the nitrogen atom in the aromatic ring. The nitrogen atom deshields the ortho and para protons due to its electronegativity and the inductive effect, causing their signals to appear downfield compared to benzene. Typically,
