Question

write down the oxidation number of fe and iupac name of the complex [At. No. of fe =26]​

Answer 1

The oxidation number of a free element is always 0. so of fe is 0

Answer 2

Answer:

If you are concerned about the oxidation number of element Iron (Fe), then the correct answer would be ‘0’.

Explanation:

As per the rules in chemistry, the Oxidation number of Fe as an element is considered to be Zero ‘0’.  The condition would not be the same when speaking of Iron as an compound. In its compound state, the oxidation number would generally depend on other elements that combine along with Iron.

So, it is obvious that it would not have any fixed oxidation number when in compound state. Some of the commonly used oxidation number of Fe are in compound FeCl2 (Ferric Chloride) that has an oxidation number of + 2.

In FeCl3 state the oxidation number of Fe would be + 3.
