Question

The bond order in $(\mathrm{NO}^+)$ ion is

• A. 3
• B. 2
• C. 1
• D. 2.5
• E. 1.5

Hint:

Molecules/ions with 14 electrons (like $N_2$, $CO$, $NO^+$) have a bond order of 3.

Answer 1

The Correct Option is A

Step 1: Concept
Total electrons in $NO^+$ = $7 (\text{N}) + 8 (\text{O}) - 1 (\text{charge}) = 14$ electrons.

Step 2: Meaning
14 electrons correspond to the same electronic configuration as $N_2$.

Step 3: Analysis
In Molecular Orbital Theory, a 14-electron system has a Bond Order of 3.

Step 4: Conclusion
Hence, correct answer is 3.
Final Answer: (A)
