Question

The oxoacid of sulphur that does not contain bond between sulphur atoms is ______.

Options

• H₂S₂O₇

• H₂S₂O₃

• H₂S₄O₆

• H₂S₂O₄

Answer 1

The oxoacid of sulphur that does not contain bond between sulphur atoms is H₂S₂O₇.

Explanation:

Among the given oxoacids of sulphur, pyrosulphuric acid (H₂S₂O₇) does not contain a direct bond between sulphur atoms. In contrast, other acids like thiosulphuric acid (H₂S₂O₃), dithionic acid (H₂S₂O₆), etc., have S-S bonds. Pyrosulphuric acid is formed by the condensation of two sulphuric acid molecules without an S-S bond, containing bridging oxygen atoms instead.
