KO2 is a superoxide in which, only one electron is released from the dioxygen atom and a superoxide ion is represented as O2- . So, in KO2 the oxygen atoms bear -1/2 oxidation state and they also behave as a free radical species, having an unpaired electron. ... Hence, KO2 behaves as paramagnetic molecule.

Is KO2 diamagnetic or paramagnetic?

K2O is paramagnetic while KO2 and K2O2 are diamagnetic class 12 chemistry CBSE.

Is KO2 paramagnetic compound?

We know that the substances with an odd number of electrons are paramagnetic. From molecular orbital configuration, it is clear that Potassium superoxide is a paramagnetic compound since it has one electron in its antibonding orbital.
