HClO ₄ is a stronger acid than H ₂ SO ₄ due to which of the following reasons?

Options

  1. A1, 2 and 3
  2. B1, 2 and 4
  3. C1, 3 and 4
  4. D2, 3 and 4

Correct answer

B. 1, 2 and 4

Step-by-step solution

The oxidation state of Cl in perchloric acid HClO ₄ is +7 while that of S in sulphur acid is +6 . Greater the oxidation state of the central atom, more readily is the cleavage of O - H bond. So, statements 1,2 and 4 are correct.
