What is the correct increasing order of Bronsted bases?

Options

  1. AClO ₄⁻< ClO ₃⁻< ClO ₂⁻< ClO ⁻
  2. BClO ₄⁻> ClO ₃⁻> ClO ₂⁻> ClO ⁻
  3. CClO ₃⁻< ClO ₄⁻< ClO ₂⁻< ClO ⁻
  4. DClO ⁻> ClO ₃⁻> ClO ₂⁻< ClO ₄⁻

Correct answer

A. ClO ₄⁻< ClO ₃⁻< ClO ₂⁻< ClO ⁻

Step-by-step solution

ClO ₄⁻< ClO ₃⁻< ClO ₂⁻< ClO ⁻ is the correct increasing order of Bronsted base. With increase in the number of oxygen atoms in the conjugate bases, the delocalisation of the bond becomes more and more extended. This results in decrease in the electron density. Consequently basicity also decreases.
