Formation of phenoxide ion
WebOther articles where phenoxide ion is discussed: phenol: Electrophilic aromatic substitution: Phenoxide ions, generated by treating a phenol with sodium hydroxide, are so strongly activated that they undergo electrophilic aromatic substitution even with very weak electrophiles such as carbon dioxide (CO2). This reaction is used commercially to make … WebWhat are the products formed when phenol reacts with iodomethane in presence of dilute alkali? Also, a reaction with a mechanism would be helpful.

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- … WebJan 13, 2024 · When it comes to phenol and alcohol, phenols are more acidic because of the formation of resonance stabilized phenoxide ions. Since phenoxide ion is more stable than alkoxide ion, it is a stronger acid. The stability of phenoxide ions also depends on the type of substituents attached to the phenol ring.

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.
Web2 Formation of phenoxide 3 and electron delocalization. The phenoxide ion can eliminate another electron to form a radical which also shows the phenomenon of delocalization 4-4a-4b. 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.
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 >
