NEET · Chemistry · STD 11 - 7. Redox reactions
Which of the following processes does not involve oxidation of iron?
- A Formation of \(Fe(CO)_5\) from \(Fe.\)
- B Liberation of \(H_2\) from steam by iron at high temperature.
- C Rusting of iron sheets.
- D Decolourisation of blue \(CuSO_4\) solution by iron.
Answer & Solution
Correct Answer
(A) Formation of \(Fe(CO)_5\) from \(Fe.\)
Step-by-step Solution
Detailed explanation
\(\stackrel{0}{\mathrm{Fe}}+\mathrm{H}_{2} \mathrm{O}+\mathrm{O}_{2} \rightarrow \stackrel{+3}{\mathrm{Fe}_{2} \mathrm{O}_{3}} \cdot \mathrm{xH}_{2} \mathrm{O}\) \(\stackrel{0}{\mathrm{Fe}}+\mathrm{CuSO}_{4} \rightarrow \stackrel{+2}{\mathrm{FeSO}_{4}}+\mathrm{Cu}\)
