The correct Answer is:
To solve the question regarding the nitrogen-nitrogen distance in the molecule N₂O (nitrous oxide), we need to analyze the bonding and resonance structures of the molecule. ### Step-by-Step Solution: 1. **Understanding the Structure of N₂O**: - N₂O consists of two nitrogen atoms and one oxygen atom. The molecular structure can be represented as N=N=O or N≡N-O, depending on the resonance forms. 2. **Identifying Bond Types**: - The bond between the two nitrogen atoms can either be a double bond (N=N) or a triple bond (N≡N). However, due to the presence of oxygen and the resonance structures, the actual bond order between the nitrogen atoms is not purely double or triple. 3. **Resonance Structures**: - The resonance structures of N₂O include: - N≡N-O (triple bond between the first nitrogen and the second nitrogen, single bond with oxygen) - N=N=O (double bond between the two nitrogen atoms and double bond with oxygen) - The resonance indicates that the bond order between the nitrogen atoms is an average of these bonds. 4. **Calculating the Bond Order**: - The bond order can be calculated from the resonance structures. The bond order is defined as the number of bonding pairs of electrons divided by the number of bond connections. - In the case of N₂O, the bond order between the nitrogen atoms is intermediate between a double bond and a triple bond due to resonance. 5. **Conclusion**: - Therefore, the N-N distance in N₂O pertains to an intermediate bond order, which is between that of a double bond (N=N) and a triple bond (N≡N). ### Final Answer: The nitrogen-nitrogen distance in N₂O pertains to an intermediate bond order between N=N and N≡N. **Correct Option**: Option D (Intermediate of N=N and N≡N). ---
