Vedclass · Answer

(C) Phenol is more acidic than ethanol because the phenoxide ion formed after the loss of a proton is resonance-stabilized by the benzene ring.In contrast,the ethoxide ion $(CH_3CH_2O^-)$ formed from ethanol is destabilized by the electron-donating inductive effect ($+I$ effect) of the ethyl group.Therefore,the phenoxide ion is more stable than the ethoxide ion,making phenol a stronger acid with a higher ionisation constant.

The ionisation constant of phenol is higher than that of ethanol because
