4 This preparation is referenced from: Org. Syn. Coll. Vol. 1, 394 Org. Syn. Coll. Vol. 3, 334 P-nitro benzoic acid is more acidic than benzoic acid, because nitro group have -I effect (electron withdrawing group) due which it withdraws electron toward itself and deactivate the benzene ring to electrophilic attack, therefore, carboxylic acid group easily releases H+ ion than benzoic acid. (b) Give reasons : (i) p-Nitrobenzoic acid has higher `K_(a)` value than benozic acid (ii) Acetone is soluble in water but benzophenone is not.

Infrared Fourier transform spectroscopic studies suggest that the molecules of 4-nitrobenzoic acid gets adsorbed on the surfaces of fine silver powder as carboxylate. Application 4-Nitrobenzoic acid is produced commercially by the oxidation of 4-nitrotoluene with molecular oxygen. Oxidation with 15% nitric acid at 175 °C produces the acid in 88.5% yield. /Another/ method involves the nitration and subsequent oxidation of polystyrene. 4-Nitrobenzoic acid is an organic compound with the formula C 6 H 4 (NO 2)CO 2 H. It is a pale yellow solid. It is a precursor to 4-nitrobenzoyl chloride, the precursor to the anesthetic procaine and folic acid.
