Question

Which of the following are peroxoacids of sulphur?

विकल्प

• \[\ce{H2SO5 and H2S2O8}\]

• \[\ce{H2SO5 and H2S2O7}\]

• \[\ce{H2S2O7 and H2S2O8}\]

• \[\ce{H2S2O6 and H2S2O7}\]

Answer 1

\[\ce{H2SO5 and H2S2O8}\]

Explanation:

Peroxy linkage refers to the presence of a bond between oxygen and oxygen (O – O) in a molecule.

Only \[\ce{H2SO5 and H2S2O7}\] of the sulphur oxoacids above have a peroxy linkage.
