Question

In which of the following processes, the bond order has increased and paramagnetic character has changed to diamagnetic ? (A) N2 arrow N+2 (B) NO arrow NO+ (C) O2 arrow O22- (D) O2 arrow O2+

Process Change in magnetic nature Bond Order Change N2 arrow N+2 Dia → para 3 → 2.5 NO arrow NO+ Para → Dia 2.5 → 3 O2 arrow O-22 Para → Dia 2 → 1 O2 arrow O+2 Para → Para 2 → 2.5

Process	Change in magnetic nature	Bond Order Change
$N_{2} \to N_{2}^{+}$	Dia $\to$ para	$3 \to 2.5$
$NO \to N O^{+}$	Para $\to$ Dia	$2.5 \to 3$
$O_{2} \to O_{2}^{- 2}$	Para $\to$ Dia	$2 \to 1$
$O_{2} \to O_{2}^{+}$	Para $\to$ Para	$2 \to 2.5$

Q. In which of the following processes, the bond order has increased and paramagnetic character has changed to diamagnetic ?

$N_{2} \to N_{2}^{+}$

$NO \to N O^{+}$

$O_{2} \to O_{2}^{2 -}$

$O_{2} \to O_{2}^{+}$
