Formation of phenoxide ion
WebApr 30, 2024 · In the acid-catalyzed reaction, the protonated formaldehyde is a "hot" electrophile that can react with a neutral phenol nucleophile. The base mechanism is similar to an aldol condensation. @user55119: okay, so there's electromerism on the formaldehyde, yielding an electrophilic carbon, and deprotonation of the phenol yields a phenoxide ion ...

WebApr 7, 2024 · Phenoxide ion is well established due to the resonance The oxygen is connected to sp2 carbon, which has a high electronegativity. So, the carbon will pull e- from the oxygen. And, this makes the phenoxide ion stable due to the distribution of the electronegative charge. WebApr 6, 2024 · The sodium phenoxide ion is then acidified with aqueous acid to form phenol. We can write the chemical reaction for this step as, The sodium phenoxide ion formed during the preparation of phenol from benzene sulphonic hydrolysed in presence of acid to neutralize the basic phenoxide ion and acidifies the mixture to yield phenol.

Suggest Corrections 6 Similar questions … WebMar 27, 2024 · In phenols the − O H group is attached to the carbon atom which is s p 2 hybridized, due to which the electron density on oxygen decreases. This increases the polarity of the − O H group which results in more ionization. And thus the H + ion can be easily abstracted.
WebOn the other hand, electron releasing groups, such as alkyl groups, in general, do not favour the formation of phenoxide ion resulting in a decrease in acid strength. Cresols, for example, are less acidic than phenol. Solve any question of Alcohols Phenols and Ethers with:-Patterns of problems > WebOn the basis of our studies of this compound with more specific oxidizing radicals such as N3, Tl(II), etc. it was inferred that hydroxyl radicals lead mainly to one electron oxidation at pH 10 where BP is present as the phenoxide ion.
