The species, which has the bond order same as that of F ₂ molecule is

Options

  1. AO ₂⁺
  2. BO ₂²⁻
  3. CO ₂
  4. DN ₂⁺

Correct answer

B. O ₂²⁻

Step-by-step solution

MO for the fluorine molecule, the 14 valence electrons of the fluorine atoms fill 4 bonding and 3 anti-bonding orbital thus bond order is 1 . Bond order = bonding electrons - anti - bonding electrons 2 In the same way O ₂²⁻ has 2 (6)+2=14 e⁻ So, bond order is 1 .
