Hint:To solve the given question, we should have knowledge about oxidation numbers and how to calculate it. Oxidation Number, is the number of electrons gained or lost or shared to form a compound from an element.
Some general rules that follow oxidation number are that the oxidation number of a free element is always , the oxidation number of a Group element in a compound is , a Group element in a compound is and the sum of oxidation numbers of all of the atoms in a compound is of total charge of the molecule.
Complete answer:
The first example we could look forward to was the oxidation number of in . Let the oxidation number of Chromium be . We can say that the total charge or molecule is zero.
Therefore, the oxidation number of in is .
Next one can be , so, oxidation number of is . While in the case of , it is . In , the oxidation number of is .
In case of , the oxidation number of is ;
Let the oxidation number of be . The oxidation number of the molecule as a whole is .
So, it can be calculated as :
So, the oxidation number of in is .
Note:
While calculating the oxidation number the charge on the whole molecule should be duly noted and identified. This is a crucial step which should not be messed up to find the correct oxidation state.
