The oxidation number of sulphur in S(8),...

The oxidation number of sulphur in `S_(8),S_(2)F_(2),H_(2)S and H_(2)SO_(4)` respectively are:

A

`+3,+4,+5`

B

`+5,+4,+3`

C

`+6,+3,+5`

D

`+3,+5,+4`

Text Solution

Verified by Experts

The correct Answer is:
C
O.N of S in `H_(2)SO_(4)` :
Let O.N. of S = x
`:. 2(+1)+x+4(-2)=0`
`rArr x = +6`
O.N of S in `H_(2)S_(2)O_(4)`
Let O.N. of S = x
`:. 2 (+1)+2x+4(-2)=0`
`rArr x = +3`
O.N of S in `H_(2)S_(2)O_(6)`
Let O.N of S = x
`:. 2(+1)+2x+6(-2)=0`
`rArr x = +5`.
