oxidation states available for a particular elements are normally more than the valencies
A brown complex has the formula:
`[Fe(H_(2))(O)_(5)NO]SO_(4)` the oxidation number of iron is:
In which of the following pairs there is the maximum difference in the oxidaation state of the elements other than oxygen?

A

`NO_(2) and N_(2)O_(4)`

B

`P_(2)O_(5) andP_(4)O_(10)`

C

`K_(2)mNo_(4)N_(2)O and NO`

D

`SO_(2) and SO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
O.N of N in `NO_(2)and N_(2)O_(4)` are +4 (same).
O.N of P in `P_(2)O_(5) and P_(4)O_(4) are +5(same)`
O.N of N in `N_(2)O is +1 and NO is +2 (difference=1)`
O.N of S in `SO_(2) is (+4) and SO_(3)` is (+6)(dfference=2)
