Question

A student performed the following displacement reaction:

Fe(s) + CuSO4(aq) = FeSO4(aq) + Cu (s)

Zn(s) + FeSO4(aq) = ZnSO4(aq) + Fe (s)

2Al (s) + 3ZnSO4(aq) = Al2(SO4)3(aq) + 3 Zn(s)

Arrange the followings in the increasing order of their reactivity:

(1) Al > Zn > Fe > Cu (2) Fe > Cu > Zn > Al

(3) Zn > Cu > Fe > Al (4)Al > Zn > Cu > Fe​
