Study Notes

Lewis Acids and Bases

A Lewis acid is an electron pair acceptor, which means it can accept a pair of electrons from a Lewis base.
A Lewis base is an electron pair donor, which means it can donate a pair of electrons to a Lewis acid.

Examples

Examples of Lewis bases include ammonia (NH3), water (H2O), and fluoride (F-).
Examples of Lewis acids include boron trifluoride (BF3), aluminum chloride (AlCl3), and iron(III) (Fe3+).

Lewis Adduct Formation

When a Lewis acid and a Lewis base share an electron pair furnished by the Lewis base, a Lewis adduct is formed.

Lewis Adduct Characteristics

A Lewis adduct is a compound that forms when a Lewis acid and a Lewis base combine.

Relationship between Lewis Acids and Bases

A Lewis acid and a Lewis base have a complementary relationship, where the Lewis acid accepts an electron pair and the Lewis base donates an electron pair.

Gilbert N. Lewis's Contribution

Gilbert N. Lewis introduced the terminology of Lewis acids and bases, and his work laid the foundation for understanding the concept of electron pair donation and acceptance.
