eg. 1:
In this reaction, \(BF_3\) accepts a pair of electrons from \(F^-\) to form a new covalent bond and, therefore, acts as an acid; \(F^-\) contributes a pair of electrons toward a new covalent bond with \(BF_3\) and, therefore, acts as a base.
In a reaction a species that acts as an acid according to Lewis theory is called a Lewis acid and a species that acts as a base a Lewis base.
