Study Notes
Lewis Acid and Base
- A Lewis acid is a species that accepts an electron pair to form a covalent bond.
- A Lewis base is a species that donates an electron pair to form a covalent bond.
Lewis Adduct
- A Lewis adduct is the resulting compound formed when a Lewis acid reacts with a Lewis base.
Role of Lewis Acid
- The role of a Lewis acid in a chemical reaction is to accept an electron pair from a Lewis base to form a covalent bond.
Shared Electron Pair
- The term used to describe the shared electron pair between a Lewis acid and base is a coordinate covalent bond.
Examples
- Examples of Lewis bases include ammonia (NH3) and water (H2O).
