Lewis acid-base adduct

Definition

A Lewis acid-base adduct is a compound formed when a Lewis acid and a Lewis base share an electron pair. The bond formed is a coordinate covalent bond.

5 Must Know Facts For Your Next Test

1. A Lewis acid accepts an electron pair, while a Lewis base donates an electron pair.
2. The formation of an adduct involves the creation of a coordinate covalent bond.
3. Common examples include the reaction between boron trifluoride (BF3) and ammonia (NH3).
4. Lewis acid-base interactions are crucial in many chemical reactions, including catalysis and complexation.
5. Adduct formation often changes the physical and chemical properties of the reactants.
