The calculated bond order of superoxide ion ( O ₂⁻ ) is

Options

  1. A2.5
  2. B2
  3. C1.5
  4. D1

Correct answer

C. 1.5

Step-by-step solution

The electronic configuration of O ₂⁻ is 1 s² ^ * 1 s² 2 s² ^ * 2 s² 2 p_ z ² ( 2 p_ x ²= 2 p_ y ² ) ( ^ * 2 p_ x ²= ^ * 2 p_ y ¹ ) Bond order = 10-7 2 =1.5
