Phenol conjugate base

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. … Weba of phenol is 9.95, but that of cyclohexanol is about 17. Thus, phenol is approximately 10 7 times more acidic than an alcohol of similar size and shape. Recall from Fig. 3.2, p. 113, that the pK a of an acid is decreased by stabilizing its conjugate base. The enhanced acidity of phenol is due to stabilization of its conjugate-base anion.
