Vedclass · Answer

(D) The $Bronsted-Lowry$ theory defines acids as proton $(H^+)$ donors and bases as proton acceptors.In options $A$,$B$,and $C$,there is a clear transfer of a proton from the acid to the base.In option $D$,the reaction involves the formation of a coordinate covalent bond where $NH_3$ acts as a Lewis base (electron pair donor) and $[Cu(H_2O)_4]^{2+}$ acts as a Lewis acid (electron pair acceptor).Since there is no proton transfer involved in this reaction,it cannot be described by the $Bronsted-Lowry$ definition but fits the $Lewis$ acid-base definition perfectly.Therefore,the correct option is $D$.

Which equilibrium can be described as an acid-base reaction using the Lewis acid-base definition but not using the Bronsted-Lowry definition?
