Q. The bond order in NO is 2.5 while that in $NO^{+}$ is 3. Which of the following statements is true for these two species?
A) Bond length in $NO^{+}$ is greater than in NO
B) Bond length in NO is greater than in $NO^{+}$
C) Bond length in $NO^{+}$ is equal to than in NO
D) Bond length is unpredictable
Explanation
(b)
Bond order $\propto \frac{1}{Bond\ length}$
BO of NO<BO of $NO^{+}$
$\therefore$ Bond length of NO is greater than the bond length of $NO^{+}$.
