Lewis base

{
  "id": "MLC-T-CHM-006548",
  "term": "Lewis base",
  "field": "Chemistry",
  "definition": "A molecular entity, or a corresponding chemical species, that is an electron-pair donor and can form a covalent bond by donating an electron pair to a Lewis acid. This interaction creates a Lewis adduct. Unlike a Brønsted-Lowry base, which is a proton acceptor, a Lewis base is defined by its ability to provide electrons, a property of species with lone pairs such as ammonia (NH₃) or water (H₂O).",
