MCQ
The oxidation number of sulphur in $\mathrm{S}_8, \mathrm{~S}_2 \mathrm{~F}_2$ and $\mathrm{H}_2 \mathrm{S}$ respectively are $.........$
- ✓$0, +1$ and $−2$
- B$+2, +1$ and $−2$
- C$0, +1$ and $+2$
- D$−2, +1$ and $−2$
✓
Answer
Correct option: A.
$0, +1$ and $−2$
Oxidation number of sulphur in $S_8$ is $0$.
Oxidation number of $F$ is $-1$ so oxidation number of sulphur in $\mathrm{S}_2 \mathrm{F}_2$ is $+1$.
Oxidation number of $H$ is $+1$ so oxidation number of sulphur in $\mathrm{H}_2 \mathrm{S}$ is $-2$.
Oxidation number of $F$ is $-1$ so oxidation number of sulphur in $\mathrm{S}_2 \mathrm{F}_2$ is $+1$.
Oxidation number of $H$ is $+1$ so oxidation number of sulphur in $\mathrm{H}_2 \mathrm{S}$ is $-2$.
