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

Options

  1. AO 2 → O 2 +
  2. BO 2 → O 2 2 -
  3. CNO → NO +
  4. DN 2 → N 2 +

Correct answer

C. NO → NO +

Step-by-step solution

Process Change in magnetic nature Bonad order change N 2 → N 2 + Dia → Para 3 → 2 . 5 NO → NO + Para → Dia 2 . 5 → 3 O 2 → O 2 - 2 Para → Dia 2 → 1 O 2 → O 2 + Para → Para 2 → 2 . 5
