What are the different types of bonds formed by sulphur with oxygen in thiosulfuric acid?
Options
- AOne double bond and two single bond
- BOne double bond and one single bond
- CTwo double bond and one single bond
- DTwo double bond and two single bond
Correct answer
A. One double bond and two single bond
Step-by-step solution
The molecular structure of thiosulfuric acid ( H ₂ S ₂ O ₃ ) features a central sulfur atom bonded to three oxygen atoms and one terminal sulfur atom. This sulfur-oxygen bonding consists of one S = O double bond and two S - O single bonds. HO - S - OH | S = O The central sulfur thus forms one double bond and two single bonds with oxygen atoms.
