WebPhenolate C6H5O- CID 119047 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (−OH) bonded directly to an aromatic hydrocarbon group. The simplest is phenol, C 6H 5OH. Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the molecule.
WebPhenoxides are formed by the phenol by abstraction of the hydroxyl protons. They are more acidic in nature, and have a low pKa value, and show resonance as oxygen having a negative charge, as shown below. Here, the last resonating structure destabilizes the molecule due to the negative charge at para with the alkyl group. WebRelative basicity. Phenols are more acidic than alcohols. The conjugate base of a phenol is a phenoxide or phenolate ion. Resonance stabilization of the phenoxide ion coupled with the polar effect of the benzene ring enhances the acidity of phenols by eight orders of magnitude (100,000,000 times) over cyclohexanol.
