Vedclass · Answer

(C) The acidic strength of compounds depends on the stability of their conjugate bases. Carboxylic acids are generally more acidic than phenols,and phenols are more acidic than alcohols.Among carboxylic acids,the presence of an electron-withdrawing group $(EWG)$ increases acidity by stabilizing the carboxylate anion through the inductive effect ($-I$ effect).Fluorine $(F)$ has a stronger $-I$ effect than chlorine $(Cl)$,so $Fluoroacetic \ acid$ is more acidic than $Chloroacetic \ acid$.Thus,the correct order is: $Fluoroacetic \ acid > Chloroacetic \ acid > Phenol > Ethanol$.
