Lewis base and acid

Lewis acid

an atom, ion, or molecule that accepts an electron pair to form a covalent bond

Lewis acids

molecules with incomplete valence shell

molecules or ions with complete shell but can be moved around to make room for other bonds

ions or molecules who's central atom is from period 3 or below

Lewis base

an atom, ion, or molecule that donates an electron pair to form a covalent bond

Lewis base

molecules or ions with unshared lone pairs and have a complete shell.

Lewis Neutralization

an electron pair transfer from a base to an acid

Evaluate the importance of lone pairs in determining the reactivity of Lewis acids and bases.

Lone pairs are essential for the reactivity of Lewis acids and bases. Lewis acids, like AlCl₃, lack lone pairs and accept electrons due to electron deficiency. Lewis bases, like OH⁻, have lone pairs that they can donate. These interactions drive the reactivity between acids and bases.
