In which of the following compounds, sulphur show maximum oxidation number?
Options
- AH ₂ SO ₄
- BSO ₃
- CH ₂ ~S ₂ O ₇
- DAll have same oxidation number for sulphur
Correct answer
D. All have same oxidation number for sulphur
Step-by-step solution
All have same oxidation number for sulphate, i.e +6 . (i)Oxidation number of S is aligned & H ₂ SO ₄=+2+x-8=0 & x=+6 aligned (ii) Oxidation number of S in SO ₃=x-6=0 x=+6 aligned & (iii) Oxidation number of S in H ₂ ~S ₂ O ₇ & =2+2 x-14=0 aligned aligned 2 x & =+12 x & =+6 aligned [where, x= Oxidation number sulphur (S) ]
