Question

${\mathrm{S}}_2{{\mathrm{O}}_8}^{2-}$ contains the following number of Sulfer-Oxygen bonds, while rhombic Sulphur has the following number of Sulfur-Sulfur bonds:

• A. $8\mathrm{and}6$
• B. $4\mathrm{and}6$
• C. $8\mathrm{and}8$
• D. $4\mathrm{and}8$

Answer 1

The correct option is C

$8\mathrm{and}8$

Explanation for the correct option:

C. $8\mathrm{and}8$

In ${\mathrm{S}}_2{{\mathrm{O}}_8}^{2-}$:

• In this structure the total bond between Sulfur- Oxygen is a $4$ double bonds $\mathrm{S}=\mathrm{O}$ and also has a $4$ sigma $\mathrm{\sigma }$ bond $\mathrm{S}-\mathrm{O}$.
• so the number of total bonds is $8$.

Rhombic Sulfur:

• In rhombic Sulfur, there is a $8$ Sulfur-Sulfur $(\mathrm{S}-\mathrm{S})$ bond present.

Hence, the total bonding in ${\mathrm{S}}_2{{\mathrm{O}}_8}^{2-}$ and Rhombic Sulfur are $8\mathrm{and}8$ respectively.
