Phenol – Properties, Structure Reaction and Uses - Vedantu

WebPhenols are chemical compounds that have a benzene ring that is linked to a hydroxyl group. They are sometimes referred to as carbolic acids due to their extreme acidity. Phenoxide is formed when phenols react with active metals such as sodium and potassium. This interaction of phenol with metals suggests that it is acidic. 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.
