13C-NMR of aniline: Why are carbons that are further from the amine group more downfield than carbons that are closer?
Although the nitrogen atom is more electronegative than carbon, nitrogen will readily share its electron pair, allowing one to draw a resonance structure where the nitrogen is donating electron density into the ring. Therefore, the donating of the lone pair of electrons overcomes the inductive effects arising from the difference in electronegativity.
