Chem 341 Jasperse Ch. 1 Structure + Intro 13 More Detailed Discussion of Acid/Base Patterns/Factors to remember 1. Charge Factor: central atom being equal, cations are more acidic than neutrals (H3O+ > H2O, NH4+ > NH3), and anions more basic than neutrals (hydroxide > water). 2. Electronegativity Factor: • Acidity H-C < H-N < H-O < H-X (halogen) • Anion Stability • Basicity • Electronegativity • Why: All neutral acids produce an anion after losing an H • The more stable the anion Z- that forms, the more acidic the parent H-Z will be. (The Product Stability/Reactivity principle). • The anion stability correlates the love for electrons (electronegativity). • Summary of Key Relationships: • ANION STABILITY and the ACIDITY of a neutral acid precursor. • ANION STABILITY and the BASICITY of the anion (inverse relationship) • ANION BASICITY and the ACIDITY OF THE CONJUGATE ACID are inversely related (the stronger the acidity of the parent acid, the weaker the basicity of the conjugate anion) • KEY: WHEN THINKING ABOUT ACIDITY AND BASICITY, FOCUS ON THE STABILITY OF THE ANION. 3. Resonance/Conjugation: Anion resonance is stabilizing, so an acid that gives a resonance-stabilized anion is more acidic. And an anion that forms with resonance will be more stable and less basic. • Oxygen Series Examples: Acidity: sulfuric acid > carboxylic acid > water or alcohol • Note: Resonance is normally useful as a tiebreaker between oxygen anions, nitrogen anions, or carbon anions O
