Current Question (ID: 10657)

Question:

$\text{No S-S bonds are present in?}$

Options:

1. $\text{S}_2\text{O}_3^{2-}$
2. $\text{S}_2\text{O}_4^{2-}$
3. $\text{S}_2\text{O}_5^{2-}$
4. $\text{S}_2\text{O}_7^{2-}$ (Correct)

Solution:

$\text{Hint: If the sulphur oxidation state in the anion is less than +6 it will contain an S-S bond.}$ $\text{The structures of the anion are as follows:}$ $\text{(A) S}_2\text{O}_3^{2-} \text{ structure contains an S-S bond}$ $\text{(B) S}_2\text{O}_4^{2-} \text{ structure contains an S-S bond}$ $\text{(C) S}_2\text{O}_5^{2-} \text{ structure contains an S-S bond}$ $\text{(D) S}_2\text{O}_7^{2-} \text{ structure contains one S-O-S bond but no S-S bond}$ $\text{In the structure of S}_2\text{O}_7^{2-}, \text{ one S-O-S bond but no S-S bond is present.}$ $\text{Hence, the correct answer is option 4th.}$
