Question
What is the oxidation number of iron, $\mathrm{Fe}$, in each of the following: $\mathrm{Fe}(\mathrm{CO})_{5},\left[\mathrm{Fe}(\text { dien })_{2}\right]^{3+}$, and $\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]^{+-}$ ?
Step 1
Let the charge on iron (Fe) be x. We can set up the equation as follows: \[x + 5(0) = 0\] Solving for x, we get: \[x = 0\] So, the oxidation number of iron in $\mathrm{Fe}(\mathrm{CO})_{5}$ is 0. Show more…
