Phenol anion
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. But besides that, the whole point of this video was to … WebProperties of Phenol. Acidity – Phenol is a weak acid.In an aqueous solution within the pH spectrum of approx. 8 – 12 is in equilibrium with the C 6 H 5 O-phenolate anion (also referred to as phenoxide). Resonance stabilization of the phenoxide anion by the aromatic ring is one reason why phenol is more acidic than aliphatic compounds containing a -OH …
Phenol anion
Did you know?
WebPhenol is more acidic than ethanol because in phenol lone pair of electrons are utilized in resonance stabilization so bond length between O and H atom increases and H X + ion is easily released. While in case of alcohol no resonance stabilization takes place so no release of H X + ion.
