Question 1 Report

Five metals represented by the letters V to Z are arranged in order of their reactivity as shown . V>W>X>Y>Z.
Which of the metals cannot displace Y from an aqueous solution of its salt?
Answer Details
Based on the given order of reactivity, any metal placed before Y in the sequence can displace Y from its salt, but any metal after Y cannot. Therefore, the answer is Z because it is placed after Y in the sequence of reactivity. Thus, Z cannot displace Y from its aqueous salt solution.
