In which of the following processes, the bond order increases and paramagnetic character changes to diamagnetic one?

Options

  1. AO2→O2+{O}_{2} \to {O}_{2}^{+}
  2. BO2→O22−{O}_{2} \to {O}_{2}^{2 -}
  3. CNO→NO+NO \to {NO}^{+}
  4. DN2→N2+{N}_{2} \to {N}_{2}^{+}

Correct answer

C. NO→NO+NO \to {NO}^{+}

Step-by-step solution

Process Change in magnetic nature Bonad order change
N2→N2+{N}_{2} \to {N}_{2}^{+} Dia →\to Para 3→2.53 \to 2 . 5
NO→NO+NO \to {NO}^{+} Para →\toDia 2.5→32 . 5 \to 3
O2→O2−2{O}_{2} \to {O}_{2}^{- 2} Para→\to Dia 2→12 \to 1
O2→O2+{O}_{2} \to {O}_{2}^{+} Para →\to Para 2→2.52 \to 2 . 5
