The bond order in NO is 2.5 while that in NO+ is 3

Chemical Bonding

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?

  1. Bond length is unpredictable
  2. Bond length in NO+ is equal to that in NO
  3. Bond length in NO+ is greater than in NO
  4. Bond length in NO is greater than in NO+

Answer

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.

The correct option is D.
