Arrange the following species in the increasing order of lone pairs of electrons. (A) $\mathrm{CO}$ (B) $\mathrm{NO}_2^{-}$ (C) $\mathrm{NF}_3$ (D) $\mathrm{CO}_3^{-2}$
  1. A < B < C < D
  2. B < C < A < D
  3. C < A < D < B
  4. A < B < D < C

Solution



Hence, the correct order is $\mathrm{A} < \mathrm{B} < \mathrm{D} < \mathrm{C}$. Thus, option (d) is correct.
