Which of the following is strongest Bronsted base?

Options

  1. AClO ⁻
  2. BClO ₂⁻
  3. CClO ₃⁻
  4. DClO ₄⁻

Correct answer

A. ClO ⁻

Step-by-step solution

HClO ₄ is the strongest acid among HClO , HClO ₂, HClO ₃ and HClO ₄ as more the number of oxygen atoms attached, more is the acidity of the molecule order of acidity is : HClO ClO ₂⁻> ClO ₃⁻> ClO ₄⁻
