Question

F2 is diamagnetic while O2 is paramagnetic. Explain on the basis of molecular orbital theory.

Answer 1

Answer:

because O2 has unpaired electrons in antibonding molecular orbital while F2 has no unpaired electrons in antibonding molecular orbital.

Answer 2

F2 is diamagnetic while O2 is paramagnetic.

• The molecular orbital theory states that every atom will combine and they form molecular orbits.
• Molecular orbital theory is the simplest one among all others to understand the nature of a molecule.

• This theory was proposed by Robert S. Mullikan.
• F2 undergoes diamagnetic property because they have 2 unpaired electrons in the outermost shell.
• O2 undergoes Paramagnetic property because they have 1 unpaired electron in the outermost shell.
• You can see the unpaired electrons of the O2 molecule in the below picture. and similarly F2 has a single electron in its outermost shell.
• In this way by drawing the MOT diagrams we can determine whether a molecule is paramagnetic or diamagnetic or etc.
