Structure can affect the Ka values for related acids. In the boxes below, draw the complete Lewis structure for a single ion of the conjugate base of each acid after the removal of a proton and consider the change in stability of the ion resulting from deprotonation. HINTS: Consider any increase/decrease in ability to participate in intramolecular hydrogen bonding as well as how the resulting –COO- groups in a molecule will interact with other atoms in the same molecule/ion.
