Sodium phenoxide (sodium phenolate) is an organic compound with the formula NaOC 6 H 5. 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.
Phenolates (also called phenoxides) are anions, salts, and esters of phenols, containing the phenolate ion. They may be formed by reaction of phenols with strong base. [1] Properties. Alkali metal phenolates, such as sodium phenolate hydrolyze in aqueous solution to form basic solutions. [2] .
phenol, 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 (C 6 H 5 OH), also known as benzenol, or carbolic acid.
In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (− O H) bonded directly to an aromatic hydrocarbon group. [1] The simplest is phenol, C. 6H. 5OH.
Acidic Properties of Alcohols. Alcohols, like water, are both weak bases and weak acids. In aqueous solutions, alcohols dissociate slightly by donating a hydrogen to water. This creates the alcohol's conjugate base, called an alkoxide ion (RO -), along with hydronium (H 3 O +).
Phenols are more acidic than alcohols because the phenoxide anion is resonance-stabilized. Delocalization of the negative charge over the ortho and para positions of the aromatic ring results in increased stability of the phenoxide anion relative to undissociated phenol and in a consequently lower ∆ G ° for dissociation.
Alkoxides are themselves bases that are frequently used as reagents in organic chemistry. They are named systematically by adding the - ate suffix to the name of the alcohol. Methanol becomes methanolate, for instance. Phenols are about a million times more acidic than alcohols (Table 17.1).
explain why phenols and phenoxide ions are very reactive towards electrophilic aromatic substitution (see Section 16.4 of the textbook). write an equation to illustrate the oxidation of a phenol or an arylamine to a quinone, and identify the reagents used to oxidize phenols.
A phenoxide ion is the conjugate base of phenol. It looks like: According to the Bronsted-Lowry theory of acids and bases, an acid is a molecule that donates H^+ ions, and a base is a molecule that takes them up again.
The meaning of PHENOXIDE is a salt of a phenol especially in its capacity as a weak acid.
