Question

Calculate the oxidation number of the central atom in ${\mathrm{FeCO}}_5.$

Answer 1

Calculating oxidation number of central metal atom

1. Step 1: Calculation of total charge
   ( Charge on Fe) + 5 (Charge on CO) = 0
2. Step 2: Determine the charge on CO (Carbonyl)
   Charge on CO = 0
3. Step 3: Calculating charge on Fe
   ( Charge on Fe) + 5(0) = 0
   ( Charge on Fe) = 0

Hence, the oxidation number of Fe in ${\mathrm{FeCO}}_5.$ is 0.
