MCQ
The bond order for $\text{O}^+_2,\text{C}_2$ are:
  • A
    2.5, 2
  • B
    2, 3
  • C
    3, 2
  • D
    1.5, 2.0

Answer

  1. 2.5, 2

    Explanation:

    $\text{O}^+_2$ has bond order 2.5

    $\text{B.O.}=\frac12(10-5)=\frac52$ In C2(12)

    $\text{B.O.}=\frac12(8-4)=2$

    $\text{B.O.}=\frac12(\text{N}_\text{b}-\text{N}_\text{a})$ where Nb is bonding and Na is antibonding electrons.
