SUMMARY
o-Toluic acid is a stronger acid than p-Toluic acid due to the "ortho effect," where the proximity of the methyl group to the carboxyl group allows for a stabilizing hydrogen bond-like interaction. This interaction enhances the acidity of o-Toluic acid by stabilizing its conjugate base anion more effectively than in p-Toluic acid, where the methyl group is positioned para to the carboxyl group. The discussion highlights the importance of resonance structures in determining acidity in substituted aromatic acids.
