Why is KO2 paramagnetic ? – InterviewSolution

InterviewSolution

1.	Why is KO2 paramagnetic ?
Answer» KO2 is a superoxide in which, only one electron is released from the dioxygen atom and a superoxide ion is represented as 02 . So, 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.
