Group electronegativity

{
  "id": "MLC-T-CHM-005038",
  "term": "Group electronegativity",
  "field": "Chemistry",
  "definition": "A measure of the electron-withdrawing or electron-donating ability of a substituent group within a molecule. It quantifies the tendency of a group to attract electrons towards itself when bonded to another atom. This concept extends the idea of atomic electronegativity to polyatomic fragments and influences bond polarity and chemical reactivity.",
