Question

among the following the paramagnetic compound is a)Na2O2,b)O3,c)N2O,d)kO2.​

Answer 1

Answer:

c or d

Explanation:

c)N2O is diamagnetic or paramagnetic. Though NO2 is paramagnetic, its dimer, N2O4, is diamagnetic. The two unpaired electrons in the two NO2 units get paired while forming the dimer, and so N2O4 is diamagnetic with even number of electrons.

 d)In KO2 the oxygen atoms bear -1/2 oxidation state and they also behave as a free radical species, having an unpaired electron. We know that a molecule becomes paramagnetic due to the presence of unpaired electrons. Hence, KO2 behaves as paramagnetic molecule
