Lewis bases are electron-pair donors and Brønsted bases are proton acceptors.To accept a
proton, a chemical species must have an electron pair; thus, all Lewis bases may act as Brønsted

definition of a Brønsted acid is a proton donor, and there are numerous examples of Lewis acids,
such as BF3, that do not donate protons.
