Question:

What are the different types of bonds formed by sulphur with oxygen in thiosulfuric acid?

Show Hint

Thiosulfuric acid is related to sulfuric acid, but one oxygen is replaced by sulfur. This helps in recalling its bonding pattern.
Updated On: May 14, 2026

The Correct Option is A

Solution and Explanation

Concept:
Thiosulfuric acid is obtained from sulfuric acid by replacing one oxygen atom with sulfur. Its structure contains central sulfur attached to oxygen atoms in different bonding ways.

Step 1:
Recall the structure of thiosulfuric acid.
The structure of thiosulfuric acid contains:
• one \(\text{S}=\text{O}\) double bond
• two \(\text{S}-\text{O}\) single bonds

Step 2:
Match with the options.
Thus, sulphur forms: \[ \text{one double bond and two single bonds with oxygen} \] Hence, the correct answer is:
\[ \boxed{(A)\ \text{One double bond and two single bond}} \]
