Question

Describe the structure of sulphuric acid and explain the reasons of shortening of S-O
bonds in the molecule.

Answer 1

Answer on Question #54616 – Chemistry – Inorganic Chemistry

**Task:**

Describe the structure of sulphuric acid and explain the reasons of shortening of S-O bonds in the molecule.

**Answer:**

The structure of sulfuric acid molecule is tetrahedral (Figure 1).

Figure 1 – Structure of sulfuric acid

The centre of this tetrahedral contains S-atom. Two its corners contain O-atom. They are bounded with S-atom by double bounds. S-O bound polarity causes shortening of S-O bonds in the molecule.

Other 2 corners contain OH-groups. Each of them bounded with S-atom with a single bound. OH-groups are bounded with each other with single bounds.
