In which of the following processes the bond order has increased and paramagnetic character has changed to diamagnetic?
Process | Change in magnetic nature | Bond order change |
N2→N+2 | Diamagnetic→paramagnetic | 3→2.5 |
NO→NO+ | Paramagnetic→Diamagnetic | 2.5→3 |
O2→O−22 | Paramagnetic→Diamagnetic | 2→1 |
O2→O+2 | Diamagnetic→Paramagnetic | 2→2.5 |
