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?

  • Bond length in NO+ is greater than in NO

  • Bond length is unpredictable

  • Bond length in NO+ in equal to that in NO

  • Bond length in NO is greater than in NO+

Answer

D.

Bond length in NO is greater than in NO+

Bond length is inversely proportional to bond -order bond order in NO+  = 3, NO = 2.5
Thus bond length in NO> NO+
