Q.
Assertion (A) Carboxylic acids are more acidic than phenols.
Reason (R) The carboxylate ion is less stabilised than phenoxide ion.
Aldehydes Ketones and Carboxylic Acids
Solution:
Carboxylate ion is more stable than phenoxide ion due to two equivalent resonating structures in which negative charge is at the O-atom. In phenoxide ion, negative charge is at the less-electronegative carbon atom.
Therefore, corresponding acid of the carboxylate ion, i.e. carboxylic acid is more acidic than phenol.
