Question
Explain briefly the information provided by the electronic configuration of molecules.
✓
Answer
The electronic configuration of molecules provides the following information:
Stability of molecules: If the number of electrons in bonding $MOs$ is greater than the number in antibonding $MOs$ the molecule is stable.
Magnetic nature of molecules: If all $MOs$ in a molecule are completely filled with two electrons each, the molecule is diamagnetic (i.e., repelled) by magnetic field. However, if at least one $MO$ is half$-$filled with one electron, the molecule is paramagnetic $($i. e., attracted by magnetic field$).$
Bond order of molecule: The bond order of the molecule can be calculated from the number of electrons in bonding $MOs (N_b)$ and antibonding $MOs (N_a).$
