Question
Why is nitric oxide paramagnetic in gaseous state but the solid obtained on cooling it is diamagnetic?
Advertisements
Solution
In gaseous state \[\ce{NO2}\] exists as monomer which has one unpaired electron but in solid-state it dimerises to \[\ce{N2O4}\] so no unpaired electron is left hence solid form is diamagnetic.
