Question
Write oxidation number of iron in $[Fe(CO)_5]$
✓
Answer
The charge on complex $\left[ Fe ( CO )_5\right]$ is 0 .
$\therefore$ (O.S. of $Fe +$ charge on ligands) $=0$
$\therefore( O . S$. of $Fe +6 \times$ charge of CO $)=0$
$\therefore( O . S$. of $Fe +6 \times 0)=0$
Therefore, O.S. of $Fe =0$
