Lewis Base

What is Lewis Base?

A Lewis base is a species that can donate a lone pair of electrons to a Lewis acid to form a coordinate covalent bond. Lewis bases are electron-pair donors and include ammonia (NH₃), water (H₂O), halide ions, and amines. The Lewis base–acid concept encompasses all Brønsted–Lowry bases and extends to reactions involving no proton transfer at all.
