Question

mno4 calculate oxidation number

Answer 1

+8 oxidation state of MnO4

Answer 2

Small error the compound should be MnO₄⁻

Answer:

+ 7

Explanation:

Given :

Compound :

MnO₄⁻

We have to calculate the oxidation number of Mn in  MnO₄⁻ .

We know :

O.N. of O is - 2 .

Let O.N  of Mn be z :

z - 2 × 4 = - 1     [ Net charge on compound is - 1 ]

z - 8 = - 1

z = - 1 + 8

z = + 7.

Mn has + 7 oxidation number .

In d- block Mn is only element which show highest O.N. of

having + 7 state ,

Hence we get answer .
