Phenol (systematically named Benzenol, also called carbolic acid or phenolic acid) is an aromatic organic compound with the molecular formula C6H5OH. It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (−C6H5) bonded to a hydroxy group (−OH). Mildly acidic, it requires careful … See more Phenol is an organic compound appreciably soluble in water, with about 84.2 g dissolving in 1000 mL (0.895 M). Homogeneous mixtures of phenol and water at phenol to water mass ratios of ~2.6 and higher are … See more Because of phenol's commercial importance, many methods have been developed for its production, but the cumene process is the dominant technology. See more Phenol was discovered in 1834 by Friedlieb Ferdinand Runge, who extracted it (in impure form) from coal tar. Runge called phenol "Karbolsäure" (coal-oil-acid, carbolic acid). Coal … See more Cryptanaerobacter phenolicus is a bacterium species that produces benzoate from phenol via 4-hydroxybenzoate. Rhodococcus phenolicus See more The major uses of phenol, consuming two thirds of its production, involve its conversion to precursors for plastics. Condensation with acetone gives bisphenol-A, a key precursor to polycarbonates and epoxide resins. Condensation of … See more Phenol is a normal metabolic product, excreted in quantities up to 40 mg/L in human urine. The temporal gland secretion of male elephants showed the presence of phenol and 4-methylphenol during musth. It is also one of the … See more Phenol and its vapors are corrosive to the eyes, the skin, and the respiratory tract. Its corrosive effect on skin and mucous membranes is due … See more WebPhenols can be deprotonated by NaOH because the phenolate anion is more stable than hydroxide. Therefore, phenols are soluble in aqueous solutions of sodium hydroxide. This also provides a way of separating phenols from other (non-acidic) organic substances, since the phenol can be regenerated simply by adding acid. mary lou retton scrooged
Can phenol be an electrophile or a nucelophile? - Study.com
WebIn the presence of strong nucleophiles, benzene can do a Nucleophilic Aromatic Substitution, also called S N AR. Unlike EAS, where addition is initiated by the presence of a strong electrophile, addition-elimination can also be initiated by a strong nucleophile in the presence of a good aryl leaving group. Concept #1: General Mechanism. WebApr 17, 2024 · A nickel-catalyzed cross-coupling to construct the C(sp2)–C(sp3) bond was developed from two sustainable biomass-based feedstocks: phenol derivatives with umpolung aldehydes. This strategy features the in situ generation of moisture/air-stable hydrazones from naturally abundant aldehydes, which act as alkyl nucleophiles under … WebApr 30, 2024 · Presuming that the reaction is base-catalyzed, "push" electrons toward the carbonyl by forming the anion of a phenol. In the acid-catalyzed reaction, the protonated … husqvarna gas leaf blower vacuum
