    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.
