Resonance stabilization of their conjugate base

Vedclass · Answer

(D) The conjugate base of a carboxylic acid,i.e.,the carboxylate ion,is resonance stabilized. The negative charge is delocalized over two electronegative oxygen atoms,which makes the carboxylate ion much more stable than the alkoxide or phenoxide ions. This increased stability of the conjugate base shifts the equilibrium towards the formation of $H^+$ ions,thereby increasing the acidity of carboxylic acids. The resonance structure is: $CH_3-COOH \xrightarrow{-H^+} CH_3-COO^- \leftrightarrow CH_3-COO^-$

Carboxylic acids are more acidic than phenol and alcohol. The reason for this is ......
