Vedclass · Answer

(D) Paramagnetism is observed in species containing unpaired electrons. Superoxides $(O_2^-)$ contain one unpaired electron in their antibonding molecular orbital,making them paramagnetic.$A$) $KO_2$ contains the superoxide ion $(O_2^-)$,which has an unpaired electron. Thus,it is paramagnetic.$B$) $K_2O_2$ contains the peroxide ion $(O_2^{2-})$,where all electrons are paired. Thus,it is diamagnetic.$C$) $RbO_2$ contains the superoxide ion $(O_2^-)$,which has an unpaired electron. Thus,it is paramagnetic.Therefore,both $KO_2$ and $RbO_2$ are paramagnetic. The correct option is $(D)$.

Which of the following compounds are paramagnetic in nature?
