Text Solution
Verified by ExpertsThe correct answer is:
C
Due to formation of more stable conjugate base after removal of H from phenol, therefore
phenol is more stable than alcohol. On the other hand, carboxylic acid is more acidic than phenol due to formation of more stable conjugate base after removal of H as compared to phenol. Chloroacetic acid is more acidic than acetic acid due to the presence of electron withdrawing chlorine group attached to a carbon of carboxylic acid.
