Lewis Acid and Base Theory

In the early 1900s, Gilbert N. Lewis, one of the well-known American chemists, introduced the concept of Lewis acids and bases. Today, his theory has led us to a better understanding of what acids and bases are and has been able to get explanations for many chemical reactions, which remained unclear.

Hybridization is the mixing of atomic orbitals to form new hybrid orbitals, which are suitable for chemical bonding. The total number of atomic orbitals before mixing always equals the number of newly formed hybrid orbitals. In methane, four atomic orbitals (one 2s and three 2p) mix to form four sp3 hybrid orbitals—we will explain this in detail later on.
