Vedclass · Answer

(A) For each transformation,we calculate the bond order $(BO)$ and magnetic behavior:$(a)$ $C^{+}_2$ ($7$ electrons,$\sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \pi 2p^1$,$BO = (5-2)/2 = 1.5$,paramagnetic) $	o C_2$ ($8$ electrons,$\sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \pi 2p^2$,$BO = (6-2)/2 = 2.0$,diamagnetic). Here,$BO$ increases and magnetic behavior changes.$(b)$ $NO^{+}$ ($14$ electrons,$BO = 3.0$,diamagnetic) $	o NO$ ($15$ electrons,$BO = 2.5$,paramagnetic). Here,$BO$ decreases.$(c)$ $O_2$ ($16$ electrons,$BO = 2.0$,paramagnetic) $	o O^{+}_2$ ($15$ electrons,$BO = 2.5$,paramagnetic). Here,$BO$ increases but magnetic behavior remains paramagnetic.$(d)$ $N_2$ ($14$ electrons,$BO = 3.0$,diamagnetic) $	o N^{+}_2$ ($13$ electrons,$BO = 2.5$,paramagnetic). Here,$BO$ decreases.

In which of the following transformations,the bond order has increased and the magnetic behaviour has changed?
