Paramagnetic Molecules
Paramagnetic molecules are those molecules that have unpaired electrons in their orbitals. These unpaired electrons are attracted to a magnetic field, and this property is used in many analytical techniques, such as magnetic resonance imaging (MRI). However, not all molecules with unpaired electrons are paramagnetic.
Correct option
The correct option is D, repelled by the magnetic field. This is because paramagnetic molecules are attracted to a magnetic field and not repelled by it. Therefore, option D is not true about paramagnetic molecules.
Other options
Let us take a look at the other options and how they are related to paramagnetic molecules.
a) Attracted by the magnetic field
As mentioned earlier, paramagnetic molecules are attracted to a magnetic field. This is because the unpaired electrons in the molecule align themselves with the magnetic field and create a net magnetic moment. This net magnetic moment causes the molecule to be attracted to the magnetic field.
b) A molecular orbital is singly occupied
In paramagnetic molecules, there is at least one unpaired electron in a molecular orbital. This means that the molecular orbital is singly occupied by an electron. This is one of the defining characteristics of a paramagnetic molecule.
c) An example is oxygen molecule
Oxygen molecule is an example of a paramagnetic molecule. It has two unpaired electrons in its molecular orbitals, making it paramagnetic.
Conclusion
In conclusion, paramagnetic molecules are those that have unpaired electrons in their orbitals, and they are attracted to a magnetic field. A molecular orbital in a paramagnetic molecule is singly occupied, and an example of a paramagnetic molecule is the oxygen molecule.

Paramagnetic molecules are attracted by the magnetic field and orbitals are singly occupied. O2 is an example. Whereas diamagnetic molecules are repelled by the magnetic field, so the option is wrong.
