The hybridization of the nitrogen atom in aniline is best described as sp2. This is due to the nitrogen's involvement in the aromatic system of the benzene ring, which requires planarity for aromaticity. While some may argue for sp3 hybridization, the sp2 designation is more accurate as it reflects the nitrogen's role in resonance with the aromatic system. All atoms in aniline must be planar to satisfy the planarity rule for aromatic compounds.
