The molecules NO2 and N2O4 are respectively:a)Diamagnetic, Paramagneti...
Paramagnetism is due to the presence of at least one unpaired electron in the molecule. ... Though NO2 is paramagnetic, its dimer, N2O4, is diamagnetic. The two unpaired electrons in the two NO2 units get paired while forming the dimer, and so N2O4 is diamagnetic with even number of electrons.

The molecules NO2 and N2O4 are respectively:a)Diamagnetic, Paramagneti...
Explanation:
NO2 and N2O4 are both nitrogen oxides, but they have different molecular structures and electron configurations.
NO2:
- NO2 consists of one nitrogen atom and two oxygen atoms.
- The nitrogen atom has five valence electrons, while each oxygen atom has six valence electrons.
- The Lewis structure of NO2 shows that the nitrogen atom forms a double bond with one of the oxygen atoms, and a single bond with the other oxygen atom.
- This arrangement gives the nitrogen atom a lone pair of electrons.
- The molecule has an odd number of electrons, which makes it a paramagnetic molecule.
N2O4:
- N2O4 consists of two nitrogen atoms and four oxygen atoms.
- The Lewis structure of N2O4 shows that the two nitrogen atoms are connected by a double bond, and each nitrogen atom is bonded to two oxygen atoms.
- Each nitrogen atom has a lone pair of electrons.
- The molecule has an even number of electrons, which makes it a diamagnetic molecule.
Paramagnetic:
- Paramagnetic molecules have unpaired electrons, which means they are attracted to a magnetic field.
- In paramagnetic molecules, the electron spins are not paired and the molecule has a net magnetic moment.
Diamagnetic:
- Diamagnetic molecules have all paired electrons, which means they are not attracted to a magnetic field.
- In diamagnetic molecules, the electron spins are paired and the molecule has no net magnetic moment.
Conclusion:
- Based on the electron configurations and molecular structures of NO2 and N2O4, it can be concluded that NO2 is paramagnetic and N2O4 is diamagnetic.
