. The oxidation number of Ni in is
The oxidation number of Ni in is + 2 .Ni(CO)4
D: None of these
Solution: Option B is the correct answer.
Explanation: The oxidation number also known as oxidation state which describes the degree of oxidation i.e. loss of electrons of an atom in a chemical compound. Conceptually the oxidation state may be positive, negative or zero.
Step 1: Let oxidation number of nickel is x and oxidation number of carbonyl group is 0.
Step 2: Now by putting the value we can find the oxidation number of nickel
Thus, option B is the correct answer. The oxidation number of Ni in is 0, so given statement is false. Ni(CO)4
