Paramagnetism | MCQs

Explanation

O₂ (oxygen molecule) is paramagnetic because it has unpaired electrons in its molecular orbitals.

According to Molecular Orbital Theory (MOT), the electronic configuration of O₂ reveals 

There are two unpaired electrons in the π* anti-bonding orbitals, which are responsible for its paramagnetic properties.

Hybridization and resonance do not directly explain the presence of unpaired electrons in this context.

Explanation

Paramagnetic compounds are attracted by a magnetic field.

Due to the presence of unpaired electrons.

Explanation

With an increase in the number of unpaired electrons, paramagnetism increases. 

Paramagnetism is directly related to the presence of unpaired electrons.

More unpaired electrons mean a stronger magnetic field, hence a greater degree of paramagnetism. 

Explanation

Paramagnetism is due to the presence of one or more unpaired electrons which are attracted by the magnetic field

Due to their spin, unpaired electrons have a magnetic dipole moment and act like tiny magnets.

Explanation

Paramagnetism is due to unpaired electrons in the material

At least one unpaired electron spin in a material's atoms or molecules causes paramagnetism. 

To put it in another way, any substance with atoms with partially filled atomic orbitals is paramagnetic.

The unpaired electrons have a magnetic dipole moment due to their spin.
