Phenol react with na
WebSodium 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 . Synthesis and structure [ edit] WebPhenols react with metals such as Na, K, Al, etc., to form phenoxide with the release of the hydrogen gas. Apart from active metals, phenol gives sodium phenoxide on reaction with aqueous NaOH(sodium hydroxide) too, by releasing a water molecule. Phenols are Bronsted acids, so they donate a proton to a stronger base like NaOH.

WebAlcohol Reactions. The functional group of the alcohols is the hydroxyl group, –OH. Unlike the alkyl halides, this group has two reactive covalent bonds, the C–O bond and the O–H bond. The electronegativity of oxygen is substantially greater than that of carbon and hydrogen. Consequently, the covalent bonds of this functional group are ...
