Q4 / 160 · TS EAMCET 2023 (13 May Shift 1) · Chemistry

From the following, identify the ions with same bond order. I. $\mathrm{CN}^{-}$ II. $\mathrm{N}_2^{+}$ III. $\mathrm{O}_2{ }^{2-}$ IV. $\mathrm{NO}^{+}$

  • A
    I \& II only
  • B
    II \& III only
  • Correct answer
    C
    I \& IV only
  • D
    I \& III only

Solution

The bond order will be same for the species having the same total number of electrons. Thus, $\mathrm{CN}^{-}$and $\mathrm{NO}^{+}$will have the same bond order as they both have a total of 14 electrons.

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