Question

The oxidation number of sulphur in $S_8,S_2{F}_2$ and $H_{2}S$ respectively are__________.

• A. $0,+1$ and $-2$
• B. $+2,+1$ and $-2$
• C. $0,+1$ and $+2$
• D. $-2,+1$ and $-2$

Answer 1

The correct option is 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 $S_2{F}_2$ is +1.

Oxidation number of $H$ is +1 so oxidation number of sulphur in $H_{2}S$ is -2.
