MCQ
In which of the following transformations, the bond order has increased and the  magnetic behaviour has changed?
  • A
    $C^+_2 \to C_2$
  • B
    $NO^+ \to NO$
  • C
    $O_2 \to O^+_2$
  • D
    $N_2 \to N^+_2$

Answer

$(a)$ $\mathop {\mathop {C_2^ + }\limits_{BO = 1.5} }\limits_{Paramagnetic}  \to \mathop {\mathop {{C_2}}\limits_{BO = 2} }\limits_{Diamagnetic} $

$(b)$ $\mathop {\mathop {N{O^ + }}\limits_{BO = 3} }\limits_{Diamagnetic}  \to \mathop {\mathop {NO}\limits_{BO = 2.5} }\limits_{Paramagnetic} $

$(c)$ $\mathop {\mathop {{O_2}}\limits_{BO = 2} }\limits_{Paramagnetic}  \to \mathop {\mathop {O_2^ + }\limits_{BO = 2.5} }\limits_{Paramagnetic} $

$(d)$ $\mathop {\mathop {{N_2}}\limits_{BO = 3} }\limits_{Diamagnetic}  \to \mathop {\mathop {N_2^ + }\limits_{BO = 2.5} }\limits_{Paramagnetic} $
