Document Summary
Section 3. 1: intro to br nsted-lowry acids and bases: a br nsted-lowry acid is a proton donor, while a br nsted-lowry base is a proton acceptor. Bronzed-lowry deals in proton transfers: br nsted-lowry acid-base reactions create a conjugate acid and a con- jugate base. Section 3. 4: br nsted-lowry acidity: qualitative perspective: relative acidity is predicable by analyzing the structure of the conjugate base with out using pka values. If a- is very stable, then ha must be a strong acid. For elements in the same row of the periodic table, electronegativity is the dominant effect. For elements in the same column, size is the dominant effect. Thus, it is makes a acidic compound relative to deprotonated carbon: resonance a negative charge is stabilized by resonance. Thus a molecule with a carboxyl group is more acidic because the charge has resonance over the ho-c=o group: induction electron-withdrawing groups, such as halogens, stabilize a nearby negative charge via induction.
