  "term": "Reactivity index",
  "field": "Chemistry",
  "definition": "A theoretical parameter derived from quantum chemical calculations that quantifies the susceptibility of a specific atom or bond within a molecule to undergo a particular type of chemical reaction. These indices are used to predict the most probable sites for electrophilic, nucleophilic, or radical attack. Examples include frontier electron densities or superdelocalizability values.",
