Question

What is the bond order in \(\mathrm{N_2}\) molecule?

• A. \(2\)
• B. zero
• C. \(1\)
• D. \(3\)

Hint:

A higher bond order indicates greater bond strength and stability.

Answer 1

The Correct Option is D

Step 1: Write the electronic configuration.
Nitrogen molecule has a total of 14 electrons.
Step 2: Apply molecular orbital theory.
In \(\mathrm{N_2}\), there are 10 electrons in bonding molecular orbitals and 4 electrons in antibonding molecular orbitals.
Step 3: Calculate bond order.
\[ \text{Bond order} = \frac{N_b - N_a}{2} = \frac{10 - 4}{2} = 3 \]
Step 4: Conclusion.
Hence, the bond order of the nitrogen molecule is \(3\).
