WebJan 28, 2024 · The electrostatic potential maps below compare the phenoxide ion to an unconjugated alkoxide. The negative charge of the phenoxide ion, show as a yellow/orange color, is delocalized from oxygen into the aromatic ring (seen by the growing red color in the phenoxide ring). Acidity of Substituted Phenols WebMar 8, 2024 · Phenols with electron-withdrawing substituents like the nitro group are more acidic because these substituents delocalize the negative charge. This effect is more pronounced when such a group is present at ortho or para positions. It is due to the effective delocalization of negative charge in phenoxide ions.

WebPhosphorus pentoxide. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Phosphorus pentoxide is a chemical compound with molecular formula P 4 O 10 (with its common name derived from its empirical formula, P 2 O 5 ). This white crystalline solid is the anhydride of phosphoric acid. WebPhenol is quite a weak acid (pKa ~10) so it's likely phenoxide would react with a hydrogen ion or water if given the chance.

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.

WebMar 28, 2015 · Resonance structure D illustrates the p -methyl case.
