Webphenol, any of a family of organic compounds characterized by a hydroxyl (―OH) group attached to a carbon atom that is part of an aromatic ring. Besides serving as the generic name for the entire family, the term phenol is also the specific name for its simplest member, monohydroxybenzene (C6H5OH), also known as benzenol, or carbolic acid. … WebOne has the phenol cation hydrogen-bonded to the ammonia nitrogen, via the hydroxy proton (C6H5OH+ - NH3). In the other, the proton has transferred to the nitrogen, and the structure is ammonium cation hydrogen-bonded to the oxygen on a phenoxy radical (C6H5O - NH4+). medial meniscus repair protocol brigham
