Question

Between ortho-nitro benzoic acid and para-nitro benzoic acid which of its conjugate base is more stable and why?

Answer 1

Conjugate base of ortho-nitro benzoic acid is more stable
than Conjugate base of para-nitro benzoic acid, because
nitro group present at Ortho position which has more
resonance and -I ( inductive) as compare to nitro group
present para position. SO Conjugate base formed from
nitro benzoic acid is stablized.
