Question

(1) What would be the correct order if Zn, Fe, Al and Cu are arranged in increasing order of reactivity? (a) Cu, Fe, Zn, Al (b) Al, Cu, Fe, Zn (c) Zn, Al, Cu, Fe (d) Fe, Zn, Al, Cu​

Answer 1

Answer:-

The correct order if Zn, Fe, Al and Cu are arranged in increasing order of reactivity is :

Al, Zn, Fe, Cu

Answer 2

Answer:

Cu,Fe,Zn,Al

Explanation:

In any reaction, Cu is the least reactive. then it is displaced by iron. Zinc is more reactive compared to iron.Then it is displaced. Aluminium is more reactive compared to Zinc. Hence the increasing order of reactivity is Cu, Fe, Zn, Al .
