Arrange the following species in the increasing order of lone pairs of electrons. (A) CO (B) NO ₂⁻ (C) NF ₃ (D) CO ₃⁻²

Options

  1. AA < B < C < D
  2. BB < C < A < D
  3. CC < A < D < B
  4. DA < B < D < C

Correct answer

D. A < B < D < C

Step-by-step solution

Hence, the correct order is A < B < D < C . Thus, option (d) is correct.
