$C_6H_5NH_3^+ + C_6H_5OH \rightleftharpoons C_6H_5NH_2 + C_6H_5OH_2^+$

Vedclass · Answer

(D) Acid-base equilibrium always favors the formation of the weaker acid and weaker base. In option $(d)$,the reactant acid is the anilinium ion ($C_6H_5NH_3^+$,$pK_a \approx 4.6$) and the product acid is the phenyloxonium ion ($C_6H_5OH_2^+$,$pK_a Since the anilinium ion is a much weaker acid than the phenyloxonium ion,the equilibrium lies to the left (reactant side). Therefore,the backward reaction is favoured.

In which of the following reactions is the backward reaction favoured?
