Conjugate acid of phenoxide

Sodium phenoxide (sodium phenolate) is an organic compound with the formula NaOC6H5. It is a white crystalline solid. Its anion, phenoxide, also known as phenolate, is the conjugate base of phenol. It is used as a precursor to many other organic compounds, such as aryl ethers. See more Most commonly, solutions of sodium phenoxide are produced by treating phenol with sodium hydroxide. Anhydrous derivatives can be prepared by combining phenol and sodium. A related, updated procedure uses … See more Sodium phenoxide is a moderately strong base. Acidification gives phenol: PhOH ⇌ PhO + H (K = 10 ) The acid-base behavior is complicated by homoassociation, … See more Like other sodium alkoxides, solid sodium phenoxide adopts a complex structure involving multiple Na-O bonds.
