Question

if Cu, Fe, Zn, Al elements are arranged in increasing order of their reactivity

Then the correct order would be which of the following?

a) Cu, Fe, Zn, Al b) Al, Cu, Fe, Zn c) Zn, Al, Cu, Fe d) Fe, Zn, Al, Cu​

Answer 1

Answer:

Cu, Fe, Zn and Al is the correct order if all of these are arranged in their increasing order of reactivity. In any reaction, Copper is the least reactive. ... Then comes Aluminium which is highly reactive and is the most reactive of all elements. So the order will be Cu, Fe, Zn, Al.
