The sum of oxidation state of the metals in Fe ( CO ) 5 , VO 2 + and WO 3 is

Step-by-step solution

In the complex Fe ( CO ) 5 , take the oxidation number of Fe be x . Carbonyl is a neutral ligand which doesn't have any charge. So the oxidation number of Fe would be x - 0 × 5   =   0 =   0   Hence, the oxidation number of iron in this complex is   0 . let oxidation state of vanadium in VO 2 +   =   x . so,           x   +   ( - 2 )   =   + 2     ⇒ x   =   + 2   +   2   =   + 4 Tun
