In which of the following coordination compounds, the central metal ion is in zero oxidation state?
- A \(\left[\mathrm{Fe}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right] \mathrm{Cl}_3\)
- B \(\mathrm{K}_4\left[\mathrm{Fe}(\mathrm{CN})_6\right]\)
- C \(\mathrm{Fe}(\mathrm{CO})_5\)
- D \(\left[\mathrm{Fe}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right] \mathrm{Cl}_2\)
Answer & Solution
Correct Answer
(C) \(\mathrm{Fe}(\mathrm{CO})_5\)
Step-by-step Solution
Detailed explanation
Let oxidation state of \(\mathrm{Fe}=x\) For \(\mathrm{Fe}(\mathrm{CO})_5, x+(5 \times 0)=0\) \(\Rightarrow \quad x=0\)
