MCQ
Sulphur has lowest oxidation number in
- A${H_2}S{O_3}$
- B$S{O_2}$
- C${H_2}S{O_4}$
- ✓${H_2}S$
✓
Answer
Correct option: D.
${H_2}S$
(d) $\mathop {{H_2}S{O_3}}\limits^{\,\, * } = + 4$; $\mathop {S{O_2}}\limits^{ * \,\,\,\,\,\,} = + 4$
$\mathop {{H_2}S{O_4}}\limits^{\,\, * } = + 6$; $\mathop {{H_2}S}\limits^{\,\,\,\,\,\,\,\,\, * } = - 2$.
