WebPhenols are more acidic than typical alcohols. The acidity of the hydroxyl group in phenols is commonly intermediate between that of aliphatic alcohols and carboxylic acids (their … WebPhenol is therefore only very weakly acidic. Ethanol Ethanol, CH 3 CH 2 OH, is so weakly acidic that you would hardly count it as acidic at all. If the hydrogen-oxygen bond breaks to release a hydrogen ion, an ethoxide ion is formed: This has nothing at all going for it.

WebSmaller natural phenols formed individual peaks while tannins form a hump. Phosphomolybdic acid is used as a reagent for staining phenolics in thin layer chromatography. Polyphenols can be studied by spectroscopy, especially in the ultraviolet domain, by fractionation or paper chromatography. 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. Share Improve this answer Follow edited Jan 6, 2016 at 10:15 at grandpas
