The bond order of $$NO$$ is $$2.5$$ while that of $$NO^{+}$$ is $$3$$. Which of the following statements is true for these two species?

ABond length in $$NO^{+}$$ is equal to that in $$NO$$.
BBond length in $$NO$$ is greater than that in $$NO^{+}$$.
Correct Answer
CBond length in $$NO^{+}$$ is greater than that in $$NO$$.
DBond length is unpredictable.

Solution

Higher the bond order, shorter will be the bond length, thus $$NO^+$$ having the higher bond order that is 3 as comapared to NO having bond order 2 so $$NO^+$$ has shorter bond length.

Bond length $$ \propto \dfrac {1}{\text{Bond order} } $$

So, bond length in $$NO$$ is greater than that in $$NO^+$$ since bond order of $$NO^+>NO.$$
