Question

A metal X can displace metal Y from its salt solution. Another metal Z can displace metal Y but not metal X from their respective salt solutions. Determine the correct order of reactivity of the given metals.

• A. Z > Y > X
• B. X > Z > Y
• C. Y > Z > X
• D. Z > X > Y

Answer 1

The correct option is B X > Z > Y

$\bullet$ X can displace Y ⇒ X is more reactive than Y

$\bullet$ Z can displace Y ⇒ Z is more reactive than Y

$\bullet$ Z cannot displace X ⇒ Z is less reactive than X

So, the overall order of reactivity is:
X > Z > Y
