Exemplar Problems

Problem 21 : Discuss the concept of a Lewis acid and a Lewis base. Provide examples of Lewis acid-base reactions.
Solution :

Lewis acids can accept an electron pair to form a covalent bond, e.g., BF₃. Lewis bases can donate an electron pair to form a covalent bond, e.g., NH₃. An example of a Lewis acid-base reaction is the formation of a coordination complex like Ag⁺ + 2NH₃ → [Ag(NH₃)₂]⁺.
