Contorted aromatics, also known as contorted or distorted aromatic compounds, refer to aromatic systems that deviate from the typical planar geometry associated with traditional aromatic compounds. In standard aromatic structures, such as benzene, the resonance and delocalization of electrons contribute to a stable, planar configuration, which allows for maximum overlap of p-orbitals. Contorted aromatics, on the other hand, exhibit non-planarity due to structural distortions, substitutions, or steric hindrance.
