delokalisaatioon
Delokalisaatioon is the phenomenon in chemistry where electron density is spread over several atoms rather than being confined to a single bond or localized pair. It describes how certain electrons, typically pi electrons in conjugated systems or lone pairs in specific arrangements, are distributed over a framework of atoms, leading to stabilization of the whole system.
In organic chemistry, delokalisaatio occurs in conjugated and aromatic systems. Classical resonance shows multiple Lewis structures
Beyond organic molecules, delokalisaatio is also important in inorganic and solid-state chemistry. In metals, valence electrons
Evidence for delokalisaatio includes bond-length equalization, characteristic spectroscopy, and computational orbitals showing lower energy for delocalized
