MCQ
Which of the following pairs have identical values of bond order ?
  • ✓
    $N_2^+$ and $O_2^+$
  • B
    $F_2$ and $Ne_2$
  • C
    $O_2$ and $B_2$
  • D
    $C_2$ and $N_2$
✓

Answer

Correct option: A.
$N_2^+$ and $O_2^+$
a
$(1)$ Bond order of $N_2^+ = 2.5$ ; The bond order of $O_2^+ 1/2\, (10 -5) = 2.5$.
$(2)$ Bond order of $F_2 = 1$ ; The bond order of $Ne_2 = 0$.
$(3)$ Bond order of $O_2 = 2$ ; The bond order of $B_2 = 1$.
$(4)$ Bond order of $C_2 = 2$ ; The bond order of $N_2 = 3$.
