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).
