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_2 O_(4)^(2-) lt SO_(3)^(2-) lt S_2 O_(6)^(2-)`
B. `SO_(3)^(2-) lt S_2 O_(4)^(2-) lt S_2 O_(6)^(2-)`
C. `S_2 O_(4)^(2-) lt SO_(6)^(2-) lt S_2 O_(3)^(2-)`
D. `S_2 O_(6 )^(2-) lt S_2 O_(6)^(2-) lt S O_(3)^(2-)`

Answer

A

Explanation

`overset(x-2)((SO_3 )^(2-)) ,x -6 =-2 , x=+4`
` overset(x-2)((S_2 O_4 )^(2-), 2x - 8 =- 2 , x= + 3 `
` overset(x-2) (S_2 O_(6))^(2-) .2x - 12 =-2 , x = + 5`
