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 _____
Correct Answer: 6
Solution and Explanation
\(\text{AgNO}_3 \rightarrow 2\text{Ag} + 2\text{NO}_2 + \frac{1}{2}\text{O}_2\)
- 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

Molecular Orbital Theory
The Molecular Orbital Theory is a more sophisticated model of chemical bonding where new molecular orbitals are generated using a mathematical process called Linear Combination of Atomic Orbitals (LCAO).
Molecular Orbital theory is a chemical bonding theory that states that individual atoms combine together to form molecular orbitals. Due to this arrangement in MOT Theory, electrons associated with different nuclei can be found in different atomic orbitals. In molecular orbital theory, the electrons present in a molecule are not assigned to individual chemical bonds between the atoms. Rather, they are treated as moving under the influence of the atomic nuclei in the entire molecule.
