4.Chemical Bonding and Molecular Structure
hard
In which of the following processes, the bond order has increased and paramagnetic character has changed to diamagnetic?
A
$NO\,\to \,NO^+$
B
$N_2\,\to \,N_2^+$
C
$O_2\,\to \,O_2^+$
D
$O_2\,\to \,O_2^{2-}$
(JEE MAIN-2019)
Solution
$B.O$ $\mathop {\mathop {NO}\limits_{0.5} }\limits_{Para} \to \mathop {\mathop {N{O^ + }}\limits_3 }\limits_{Dia} $ $B.O$ $\mathop {\mathop {{N_2}}\limits_3 }\limits_{Dia} \to \mathop {\mathop {N_2^ + }\limits_{2.5} }\limits_{Para} $
$B.O$ $\mathop {\mathop {{O_2}}\limits_2 }\limits_{Para} \to \mathop {\mathop {O_2^ + }\limits_{2.5} }\limits_{Para} $ $B.O$ $\mathop {\mathop {{O_2}}\limits_2 }\limits_{Para} \to \mathop {\mathop {O_2^{2 – }}\limits_1 }\limits_{Dia} $
