What is Phenol? Medical Uses, Health Benefits, and Risks

WebPhenols are weakly acidic (pKa = 10) because of their resonance stabilized conjugate base, phenoxide. Alcohols are considered neutral with pKa values similar to water (pKa = 14). … WebPhenols are considerably more acidic than alcohols. For example, the pK a 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. scruples lounge bridgeport ct https://simul-fortes.com
