WebThe resonance structures are the hypothetical structures of the conjugated compounds which are used to explain the movement of electrons. The actual structure of the conjugated compound is a resultant hybrid of all the resonating structures. This phenomenon is known as delocalisation, mesomerism or the resonance.
In chemistry, delocalized electrons are electrons in a molecule, ion or solid metal that are not associated with a single atom or a covalent bond. The term delocalization is general and can have slightly different meanings in different fields: • In organic chemistry, it refers to resonance in conjugated systems and aromatic compounds. • In solid-state physics, it refers to free electrons that facilitate electrical conduction. left join laravelWebDelocalisation Energy.
