66. Nitric oxide, though an odd electron molecule, is diamagnetic in liquid state.
(1991, 1M)
Show Answer
Solution:
- In liquid state, nitric oxide (NO) dimerises into (NO) $)_{2}$ and odd electrons disappear giving diamagnetic property.
$$ \underset{\text { aramagnetic }}{2 \mathrm{NO}} \longrightarrow \mathrm{O}=\underset{\text { Diamagnetic }}{\mathrm{N}-\mathrm{N}=\mathrm{O}}(l) $$
