WebJun 14, 2024 · Phenol is first deprotonated by the sodium hydroxide as you already thought. The deprotonation of Phenol is favored because the pKa of Phenol is lower than the pKa of water meaning O H X − is a stronger conjugated base than P h O X −: The formed Phenolate is a good nucleophile, and will attack the methyl groups of the Dimethyl Sulfate. WebSep 11, 2024 · Phenols are weak acids – in water, they ionize slightly to form phenoxide ion and hydronium ion, which makes the solution acidic. If phenol is reacted with NaOH (a strong base), it is completely converted to the phenoxide ion, which is soluble in water because it is charged. Phenol itself is not very soluble in water.
