WebLewis Acids and Bases • A Lewis acid accepts and shares a pair of electrons • A Lewis base donates and shares a pair of electrons • The following reaction fits both the Lewis and BL definition • Some Lewis acid/base reactions can not be classified using the BL definition Organic Chemistry, Klein, 2 nd Edition. WebA Lewis base is a substance that donates a pair of electrons to form a covalent bond. So, a Lewis acid-base reaction is represented by the transfer of a pair of electrons from a base to an acid. A hydrogen ion, which lacks any electrons, accepts a pair of electrons. It is an acid under both the Brønsted-Lowry and Lewis definitions.
