Detailed Solution

The molecular formula of pyrosulphuric acid is H₂S₂O₇. This compound, also known as disulfuric acid or oleum, is formed by combining two molecules of sulfuric acid (H₂SO₄) with the elimination of one water molecule (H₂O). The reaction can be represented as:

H₂SO₄ + SO₃ → H₂S₂O₇

In this structure, two sulfur atoms are connected through an oxygen bridge, each bonded to additional oxygen atoms and hydroxyl groups, resulting in the formula H₂S₂O₇. This configuration classifies pyrosulphuric acid as an oxyacid of sulfur.

Therefore, among the given options, H₂S₂O₇ is the correct molecular formula for pyrosulphuric acid.
