In which of the following pairs is there the greatest difference in the oxidation numbers of the underlined elements?

A

`ul(N)O_(2)` and `ul(N_(2))O_(4)`

B

`ul(S)O_(3)^(2)` and `ul(S)O_(4)^(2-)`

C

`ul(S)^(2-)` and `ul(S)O_(3)^(2-)`

D

`ul(S)^(2-)` and `ul(S)O_(4)^(2-)`

Text Solution

Verified by Experts

The correct Answer is:
D
Oxidation numbers of `S` in `S^(2-), SO_(3)^(2-), SO_(4)^(2-)`, and `S_(2)O_(3)^(2-)` are `-2, +4, +6`, and `+2`, respectively.
a. Difference in oxidation number of `N=0`
b. Difference in oxidation number of `S=2`
c. Difference in oxidation number of `S=6`
d. Difference in oxidation number of `S=8`
