Number of Unpaired Electrons in N2
Explanation:
- N2 molecule has a total of 14 electrons.
- Each N atom has 5 valence electrons, and they share three electrons to form a triple bond.
- The Lewis structure of N2 can be represented as N≡N.
- The bond order of N2 is 3, indicating a triple bond between the two nitrogen atoms.
- In the molecule, both nitrogen atoms have a stable electronic configuration, with each nitrogen atom having 3 lone pairs and a triple bond.
- The electrons in the triple bond are shared by both nitrogen atoms, and hence they are paired electrons.
- However, each nitrogen atom has one unpaired electron in the 2p orbital.
- Therefore, the total number of unpaired electrons in N2 is 1.
Hence, option (c) is the correct answer.
Note: The concept of unpaired electrons is significant in determining the magnetic behavior of molecules. In N2, the presence of one unpaired electron makes it paramagnetic, which means it is attracted to an external magnetic field.
