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

Explanation

The phenoxide ion has more number of reasonating structrures but carboxylic acid is more stronger acid than phenol since there are two electronegative oxygen atoms in carboxylate ion as compared to only one oxygen atom in phenate ion , therefore the electron charge in the carboxylate ion is more dispered in comparison to phenate ion . consequently carboxyl ion is relatively more stable as compared to phenate to phenate ion , thus the release of `H^+` ion form carboxylic acid is comparactively easier and therefore , it behaves as stronger acid than phenol ( for details
