Which of the following statements is incorrect?

Options

  1. ABond length of O ₂> Bond length of O ₂²⁺
  2. BBond order of O ₂⁺< Bond order of O ₂²⁻
  3. CBond length of O ₂> Bond length of O ₂²⁻
  4. DBond order of O ₂> Bond order of O ₂²⁻

Correct answer

B. Bond order of O ₂⁺< Bond order of O ₂²⁻

Step-by-step solution

We know that, Thus, bond order = O ₂²⁺> O ₂⁺> O ₂> O ₂⁻> O ₂²⁻ Bond length 1 Bond order Bond length = O ₂²⁺< O ₂⁺< O ₂< O ₂⁻< O ₂²⁻ Thus, the incorrect statement is given in option (b) i.e. bonds order of O ₂⁺< bond order of O ₂²⁻ .
