Question

p-nitrobenzoic acid is stronger than benzoic acid explain

Answer 1

Electron withdrawing groups{EWG} at ortho, para positions increases acidity of aromatic acids. In ortho-nitrobenzoic acid, there is hydrogen bonding. So, it is less acidic than p-nitrobenzoic acid. ... O-nitro benzoic acid is most acidic due to ortho effect.

Answer 2

According to the question;

"P-nitrobenzoic acid is stronger than benzoic acid."

This statement is completely true because;

In the benzoic acid there is a resonance effect which stabilizer is the carboxylic group present in that benzoic acid.

Since the intermolecular bond is stronger than the resonance effect the nitro benzoic acid is more stabilized and stronger in acidity parameter.
