Question

oxidation state of Mn in Mn2(CO)10​

Answer 1

Answer:

Mg O

Explanation:

break all the M-CO bonds and you are left with a bunch of carbon monoxide molecules. These have a positive and negative charge so are neutral and contribute 0 to the oxidation state. Bonds to the same element also contribute 0 to the oxidation state so the answer is Mg 0

Answer 2

Answer:

Oxidation state of MN in mn2(co)2 is zero
