Paragraph: Consider the following sequence of reactions, if A is sulphuric acid, then give the answer of following questions. Which of the following oxy acid is having S - O - S linkage ?

Options

  1. AB
  2. BC
  3. Cf
  4. DNone of these

Correct answer

A. B

Step-by-step solution

( A ) 2 H ₂ SO ₄ ( ~B ) H ₂ ~S ₂ O ₇ + H ₂ O H ₂ SO ₄ D SO ₃ + H ₂ O H ₂ SO ₄ [ O ] H ₂ SO ₅ H ₂ ~S ₂ O ₆ is hyposulphuric acid and does not have peroxy linkage. H ₂ SO ₅ (Caro's acid) and H ₂ ~S ₂ O ₈ (Marshall's acid) have one peroxy linkage each.
