Vedclass · Answer

(D) The ability to act as a reducing agent is directly proportional to the reactivity of the metal.$(1)$ Since only $C$ reacts with $HCl$ to evolve $H_{2(g)}$,$C$ is more reactive than $H_2$ and is the strongest reducing agent among the four.$(2)$ When $A$ is added to solutions of other metal ions,it displaces $D$ but not $B$ or $C$. This implies that $A$ is a stronger reducing agent than $D$,but weaker than $B$ and $C$.Combining these observations,the order of increasing reducing ability is $D Therefore,the correct option is $D$.
