Among the following, the species having the smallest bond is

Options

  1. ANO ⁻
  2. BNO ⁺
  3. CO ₂
  4. DNO

Correct answer

B. NO ⁺

Step-by-step solution

NO ⁻(16)- B.O. -2 O ₂(16)- B.O. -2 NO ⁺(14)- B.O. -3 NO (15)- B.O. -2.5 Higher the bond order lower is the bond length. Hence NO ⁺ will have smallest bond.
