Correct Answer: Acetic acid (pKa \u2248 4.8) is a stronger acid than p-toluenesulfonic acid (TsOH, pKa \u2248 7).<\/strong><\/p>\n\n\n\n Explanation:<\/strong><\/p>\n\n\n\n The pKa value of an acid measures its tendency to donate protons (H\u207a). A lower pKa value corresponds to a stronger acid because it indicates greater ease in losing a proton.<\/p>\n\n\n\n Acetic acid, with a pKa of approximately 4.8, is more acidic than p-toluenesulfonic acid (TsOH), which has a pKa of about 7. This means acetic acid donates its proton more readily than TsOH does.<\/p>\n\n\n\n Structurally, acetic acid contains a carboxylic acid group (-COOH), which can delocalize its negative charge after losing a proton through resonance with the adjacent carbonyl oxygen. This stabilization makes the conjugate base (acetate ion) relatively stable.<\/p>\n\n\n\n In contrast, p-toluenesulfonic acid has a sulfonic acid group (-SO\u2083H), which is typically very strong. However, if the given pKa of TsOH is around 7 (unusually high, as TsOH normally has a pKa around -2), it would suggest the sulfonic acid group is less acidic in this context, possibly due to specific solvent conditions or experimental data provided.<\/p>\n\n\n\n Under the provided data, the comparison of pKa values clearly shows that acetic acid (pKa 4.8) is the stronger acid than TsOH (pKa 7). This makes TsOH a weaker acid in this particular scenario, despite typical expectations.<\/p>\n\n\n\n As a result, in an acid-base equilibrium, acetic acid would more likely donate a proton than TsOH, making the reaction favor formation of the conjugate base of acetic acid and the conjugate acid of TsOH. This principle is useful in understanding acid-base reactions, buffer systems, and reaction mechanisms in organic chemistry.<\/p>\n\n\n\n ~OH 5 p-toluenesulfonic acid pKa ~7 TsOH OH acetic acid pKa 4.8 The Correct Answer and Explanation is: Correct Answer: Acetic acid (pKa \u2248 4.8) is a stronger acid than p-toluenesulfonic acid (TsOH, pKa \u2248 7).
