Which of the following processes does not involve oxidation of iron ?A

1.	Which of the following processes does not involve oxidation of iron ?A. Formation of `Fe(CO)_(5)` from FeB. Liberation of `H_(2)` from steam by iron at high temperatureC. Rusting of iron sheetsD. Decolourisation of blue `CuSO_(4)` solution by iron.
Answer» Correct Answer - A (a) Oxidation state does not change in `Fe(CO)_(5)` formed from Fe (It is zero). Therefore, there is no oxidation in this case.
