The oxidation state of `Fe` in `Fe(CO)_(5)` is

A

zero

B

`5`

C

` -5`

D

` +3`

Text Solution

Verified by Experts

The correct Answer is:
B
The algebraic sum of the oxidation numbers of all the atoms in a compound must be zero .In `Fe(CO)_5`, the oxidation number contribution fo ` CO` id zero, because it is a moleculr . Thus,
` x+5 (0) =0`
`x=0`
