Abstract
Abstract The ionization and solution enthalpies of o -methoxybenzoic acid have been measured in H 2 O-DMSO mixtures. In the same solutions, the Δ G 0 values for the ionization process have been determined by potentiometric measurements. A study of the ortho effects by means of a linear combination of the ordinary polar, proximity polar, and steric effects was also performed. The CH 3 O group seems to undergo a partial steric inhibition of resonance. Finally, the proton transfer process from the ortho derivative to benzoic acid, compared with the same process in the gaseous phase, is presented.
