Although phenoxide ion has more number of resonating structures than carboxylate ion, carboxylic acid is a stronger acid than phenol? Why?

Answer»

Solution :In carboxylate ion -ve charge is delocalised over two oxygen atoms WHEREAS in phenoxide ion the -ve charge is delocalised over one oxygen atom. Therefore carboxylate ion is more stable than phenoxide ion and that is why CARBOXYLIC acids are more acidic than PHENOLS.
