Lewis Acid
What is Lewis Acid?
A Lewis acid is a species that can accept a lone pair of electrons from a Lewis base to form a coordinate covalent bond. Lewis acids are electron-pair acceptors and include metal cations, boron trifluoride (BF₃), and aluminium chloride (AlCl₃). The Lewis acid–base concept is broader than the Brønsted–Lowry concept and explains reactions that do not involve proton transfer.
