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

Options

A. `NO_2 and N_2 O_4`
B. `SO_(3)^(2-) and SO_(4)^(2-)`
C. `S^(2-) and S_(2)O_(3)^(2-)`
D. `S^(2-) and SO_(4)^(2-)`

Answer

D

Explanation

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 inoxidation number of S=4 D) Difference in oxidation number of S=8
