WebAs we know, electron withdrawing groups increase the strength of the acid and electron donating group decreases the strength of acids. Therefore, 4-methoxybenzoic acid is the weakest acid among them and 3,4-Dinitrobenzoic acid is the strongest due to the presence of 2 electron withdrawing groups and then 4-Nitrobenzoic acid.

Web7. apr 2024 · Benzoic acid is an aromatic acid that is susceptible to the normal electrophilic benzene ring replacement reactions such as nitration. The nitration of benzoic acid thus results in the formation of a compound called 3-Nitrobenzoic acid. That is because the group "-COOH" present in benzoic acid is electron-withdrawal, thus it is meta-directing. WebIn methanol, dissociation constants of carboxylic acids, phenols, and protonated nitrogen bases show excellent correlations with corresponding values in water.
