Solution: Classify each of the following as a Lewis acid or a Lewis base.


Classify each of the following as a Lewis acid or a Lewis base.


A Lewis acid is an electron acceptor. All cations are Lewis acids (Ca+2, Fe+3). Atoms or ions that have an incomplete octet can also act as Lewis acids (BF3, AlF3). Molecules whose central atom can hold more than 8 electrons can also be electron acceptors and are classified as Lewis acids (SiF4).

A Lewis base is an electron donor. They tend to be ions that are negatively charged (F-, O2-). Molecules with electrons on their central atom (NH3) can also be Lewis bases.
