Question
NO is paramagnetic in the gaseous state but diamagnetic in the solid and liquid states. Justify?
Solution
NO has odd number of electrons (7 + 8 = 15) and due to the presence of unpaired electron, it is paramagnetic in the gaseous state.
However, in the liquid and solid states, the unpaired electrons are involved in the formation of loose dimer. In the absence of any unpaired electrons, it is diamagnetic in nature.
