概览
The para nitro group influences the stability of the phenoxide conjugate base through electron withdrawal and conjugation. Its OH and nitro groups are too far apart for the adjacent-group intramolecular hydrogen bond available to 2-nitrophenol. Substituent position therefore matters as well as functional-group identity.
