WebAug 5, 2024 · So why should p-nitrophenol be more acidic? Well, perhaps because the lone pair of the oxygen is capable of resonance with the quaternized nitrogen centre, a more stable mesomer than that available for m-nitrophenol; and thus the phenoxide anion, the conjugate base, is less charge-localized, and thus entropically favoured. WebPhenol (systematically named Benzenol, also called carbolic acid or phenolic acid) is an aromatic organic compound with the molecular formula C6H5OH.
