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

Options

  1. AOne double bond and two single bond
  2. BOne double bond and one single bond
  3. CTwo double bond and one single bond
  4. 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.
