Question

In which of the following, sulphur has the highest oxidation state?

• A. $S{O}_2$
• B. $S{O}_3$
• C. $H_{2}S{O}_4$
• D. $H_{2}S$

Answer 1

Answer: (B), (C)

The correct options are
B $H_{2}S{O}_4$
C $S{O}_3$

Sulphur has the highest oxidation state in $S{O}_3$ and $H_{2}S{O}_4$. The oxidation state of S in $S{O}_2$,
$S{O}_3$, $H_{2}S{O}_4$ and $H_{2}S$ is +4, +6, +6 and -2 respectively.
