Study Notes
Lewis Acids and Bases
- A Lewis acid is a species that accepts a pair of electrons to form a covalent bond.
- A Lewis base is a species that donates a pair of electrons to form a covalent bond.
Formation of Lewis Adducts
- In the reaction between NH3 and Me3B, a Lewis adduct is formed.
- A Lewis adduct is a compound that results from the formation of a covalent bond between a Lewis acid and a Lewis base.
Bonding in Lewis Adducts
- The bond formed in a Lewis adduct is a covalent bond, resulting from the sharing of a pair of electrons between the Lewis acid and Lewis base.
Nucleophiles and Electrophiles
- A Lewis base can also be referred to as a nucleophile, as it donates a pair of electrons to form a covalent bond.
- A Lewis acid can also be referred to as an electrophile, as it accepts a pair of electrons to form a covalent bond.
- The terms nucleophile and electrophile are related to Lewis acids and bases, as they describe the electron-donating and electron-accepting properties of these species.
