  "term": "Benzenium ions",
  "field": "Chemistry",
  "definition": "Carbocations formed by the electrophilic attack on a benzene ring, resulting in a positively charged, delocalized system. They are characterized by a sp3 hybridized carbon atom within the ring, which bears the attacking electrophile and a hydrogen atom, while the positive charge is delocalized over the remaining five carbon atoms. These arenium ions are key intermediates in electrophilic aromatic substitution reactions.",
