Q5 / 160 · AP EAMCET 2022 (08 Jul Shift 1) · Chemistry

If the bond order of $\mathrm{CO}$ is $\mathrm{x}$, the bond order of $\mathrm{O}_2^{2-}$ ion is

  • A
    $\mathrm{X}$
  • B
    $\mathrm{x} / 2$
  • Correct answer
    C
    $x / 3$
  • D
    $2 \mathrm{x}$

Solution

Bond order of $\mathrm{O}_2^{2-}=\frac{1}{2}(10-8)=1$ Bond order of $\mathrm{CO}=3=\mathrm{x}$ $\therefore \quad$ Bond order of $\mathrm{O}_2^{2-}=\frac{\mathrm{x}}{3}$

Hence, the correct answer is option: 'C'.
