Stabilization of a conjugate base: electronegativity

Webv. t. e. A conjugate acid, within the Brønsted–Lowry acid–base theory, is a chemical compound formed when an acid donates a proton ( H +) to a base —in other words, it is a base with a hydrogen ion added to it, as in the reverse reaction it loses a hydrogen ion. On the other hand, a conjugate base is what is left over after an acid has ... http://ion.chem.usu.edu/~scheiner/LundellChemistry/practiceproblems/ch11_practiceproblems.pdf
