Question

Which displacement reaction will not occur among the following reactions?
  1. Fe+CuSO4
  2. Mg+CuSO4
  3. Cu+FeSO4
  4. Zn+CuSO4

A
Zn+CuSO4
B
Cu+FeSO4
C
Fe+CuSO4
D
Mg+CuSO4
Solution
Verified by Toppr

Cu(s)+FeSO4(aq) No displacement reaction

Single displacement reaction will not occur in the given reaction because Fe is a more reactive metal than Cu and hence cannot be displaced by a less reactive metal like Cu.

Hence, the correct option is C
