MCQ
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. . . . .
- A$2$
- B$3$
- C$4$
- ✓$6$
✓
Answer
Correct option: D.
$6$
d
$AgNO _3 \rightarrow 2 Ag +2 NO _2+1 / 2 O _2$
$AgNO _3 \rightarrow 2 Ag +2 NO _2+1 / 2 O _2$
- 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 antibonding electrons $=6$
