MCQ
Number of $S - S$ bond is $H_2S_nO_6$
- A$n$
- ✓$(n - 1)$
- C$(n - 2)$
- D$(n + 1)$
✓
Answer
Correct option: B.
$(n - 1)$
b
The number of $S-S$ bonds in polythionic acid $\left(\mathrm{H}_{2} \mathrm{S}_{\mathrm{n}} \mathrm{O}_{6}\right)$ are $\mathrm{n}-1 .$
The number of $S-S$ bonds in polythionic acid $\left(\mathrm{H}_{2} \mathrm{S}_{\mathrm{n}} \mathrm{O}_{6}\right)$ are $\mathrm{n}-1 .$
Hence option $\mathrm{B}$ is correct.
