Metal A displaces metal B from a solution of its salt, and metal B displaces metal C from a solution of its salt. What is the correct order of reactivity of the metals?
Answer and explanation
Correct answer: A > B > C
In a displacement reaction, a more reactive metal removes a less reactive metal from its salt solution. Since A displaces B, A is more reactive than B, written A > B. Since B displaces C, B > C. Combining both relationships gives A > B > C, so option A is correct. Equal reactivity would not produce these displacements.
