Consider the acidity of the carboxylic acids
PhCOOH
p – NO2C6H4COOH
o – NO2C6H4COOH
o – NO2C6H4COOH
C.
o – NO2C6H4COOH
-NO2 group at any position shows electron withdrawing effect thus acid strength is increased. But o -nitro benzoate ion is stabilised by intramolecular H-bonding. Hence its acid strength is maximum. The effect is more at para position.
