Question

Oxidation state of central atom in nah2o2

Answer 1

Answer:

[Ni(CO)

4

]

2−

Central atom =Ni=Ni

Oxidation state of COCO in general =-1=−1

Applying formula, \text{Sum of total oxidation state of all atoms } = \text{ Overall charge on the compound}.Sum of total oxidation state of all atoms = Overall charge on the compound.

Let oxidation state of Ni=x\\ x+4(-1)=-2,\\x=+2Ni=x

x+4(−1)=−2,

x=+2

\therefore∴ Oxidation state of Ni=+2.Ni=+2.
