WebApr 10, 2024 · It is due to the effective delocalisation of negative charge in phenoxide ion when substituent is at ortho or para position. On the other hand. electron releasing groups, such as alkyl groups, in general, do not favour the formation of phenoxide ion resulting in decrease in acid strength. Cresols, for example, are less acidic than phenol. 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.
WebAmong carboxylic acid, phenol and alcohol. Alcohol is the least acidic while carboxylic acid is the most acidic. Phenol is more acidic than alcohol because of formation of phenoxide ion which is stabilized by resonance though the conjugate base of carboxylic acid is much more stable because the charge is being delocalized over more electronegative atom i.e … WebThis free radical undergoes decarboxylation to form methyl free radical.

WebThe acidic nature is due to formation of resonance stabilized phenoxide ion formed by losing a proton from -OH group. When alkalies are added to phenol, the above equilibrium is shifted more to the right side as the H + ions are removed by the OH - ions that are furnished by alkalies.
