Question

Bond order of $N_2^{+},N_2^{-}$ and $N_2$ will be:

• A. 2.5, 2.5 and 3 respectively
• B. 2, 2.5 and 3 respectively
• C. 3, 2.5 and 3 respectively
• D. 2.5, 2.5 and 2.5 respectively.

Answer 1

Answer: (A)

2.5, 2.5 and 3 respectively

For Figure-1, Bond order=$\frac{9-4}{2}=\frac{5}{2}=2.5$

For Figure-2, Bond order=$\frac{10-5}{2}=\frac{5}{2}=2.5$

For Figure-3, Bond order=$\frac{10-4}{2}\frac{6}{2}=3$
