Among the following which one will have the largest O - O bond length?

Options

  1. AKO ₂
  2. BO ₂
  3. CO ₂⁺ [ AsF ₆ ]⁻
  4. DK ₂ O ₂

Correct answer

D. K ₂ O ₂

Step-by-step solution

Bond order of O ₂⁻, O ₂, O ₂ ⁺ and O ₂ ²⁻ are 1.5, 2.0, 2.5 and 1.0 respectively. Bond length is inversely proportional to bond order. O - O bond length is largest in K ₂ O ₂ .
