Question

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 that in NO

(d) Bond length is unpredictable.

Answer 1

(b) : Higher the bond order, shorter will be the bond length. Thus NO⁺ is having higher bond order than that of NO so NO⁺ has shorter bond length.
