10. Protonation of carboxylic acid may occur either on the hydroxyl group or on the carbonyl oxygen to give structures 1 and 2. (5 pts) Substituent H 2 The equilibrium constants for protonation of a number of substituted benzoic acids have been determined. CO,H pk Drom OH₂ 7.26 CO₂H + H+ m-Me p-Me 7.19 6.92 K m-MeO 7.45 OH* OH p-MeO 6.68 m-Cl p-CI 7.73 7.48 m-NO₂ 7.97 Convert this to Hammet plots using ō and ō+ and by correlation of the above results with one of these graphs determine the protonation (1 or 2). Explain your answer by showing some illustrations. 10. Protonation of carboxylic acid may occur either on the hydroxyl group or on the carbonyl oxygen to give structures 1 and 2.
