CTET PAPER II 2021 · PYQ · Reactivity Series of Metals · easy
Metal 'X' displaces metal 'Y' from its salt solution but is not able to displace metal 'Z' from its salt solution. Identify the most reactive metal.
Answer
The correct answer is C: Z. In the reactivity series, a more reactive metal displaces a less reactive metal from its salt solution. Since X displaces Y, X is more reactive than Y.
A.X
B.Y
C.Z✓ Correct
D.Cannot be determined.
Explanation
In the reactivity series, a more reactive metal displaces a less reactive metal from its salt solution. Since X displaces Y, X is more reactive than Y. Since X cannot displace Z, Z is more reactive than X. Therefore the order of reactivity is Z > X > Y, making Z the most reactive metal.
