The oxidation states of sulphur in the anions `SO_(3)^(2-), S_(2)O_(4)^(2-)`, and `S_(2)O_(6)^(2-)` follow the order

Options

A. `S_2O_6^(2-) lt S_2O_4^(2-) lt SO_3^(2-)`
B. `S_2O_4^(2-) lt SO_3^(2-)ltS_2O_6^(2-) `
C. `S_2O_3^(2-) lt S_2O_4^(2-)ltS_2O_6^(2-) `
D. `S_2O_4^(2-) lt S_2O_6^(2-)ltSO_3^(2-) `

Answer

B

Explanation

`S_2O_4^(2-)ltSO_(3)^(2-)ltS_2O_6^(2-)`
Oxidation state of sulphur in `S_2O_4^(2-) =+3`
Oxidation state of sulphur in `S_2O_3^(2-) =+4`
Oxidation state of sulphur in `S_2O_6^(2-) =+5`
