Question

Thermal decomposition of $AgNO _3$ produces two paramagnetic gases. The total number of electrons present in the antibonding molecular orbitals of the gas that has the higher number of unpaired electrons is _____

Answer 1

$\text{AgNO}_3 \rightarrow 2\text{Ag} + 2\text{NO}_2 + \frac{1}{2}\text{O}_2$
- Both $NO_2​ \& O_2$​ are paramagnetic
−$NO_2$​ is odd electron molecule with one unpaired electron
−$O_2$​ has two unpaired electrons
Total number of electrons present in antibonding molecular orbitals = 6
