What is the bond order of N-N bond in N₂O?

• A. 1
• B. 1.5
• C. 2
• D. 2.5

The bond order of a bond indicates the number of chemical bonds between a pair of atoms. In the case of the nitrogen-nitrogen (N-N) bond in nitrous oxide (N₂O), we can analyze its molecular structure to determine the bond order.

Understanding Bond Order

Bond order can be calculated using the formula:

• Bond Order = (Number of bonding electrons - Number of antibonding electrons) / 2

N₂O Structure

N₂O consists of two nitrogen atoms and one oxygen atom. The nitrogen atoms are connected by a single bond, while the overall structure includes a double bond between one nitrogen and the oxygen atom.

Calculating the Bond Order

For the N-N bond in N₂O:

• There are 2 bonding electrons and no antibonding electrons in the N-N bond.
• Using the formula: (2 - 0) / 2 = 1

Final Answer

Thus, the bond order of the N-N bond in N₂O is 1. Therefore, the correct answer is A. 1.
