The bond order in NO is 2.5 while that in N O + is 3. Which of the following statements is true for these two species?

Options

  1. ABond length in N O + is equal to that in NO
  2. BBond length in N O + is greater than in NO
  3. CBond length in NO is greater than in N O +
  4. DBond length is unpredictable.

Correct answer

C. Bond length in NO is greater than in N O +

Step-by-step solution

Bond length is inversely proportional to bond–order. Bond order in N O + = 3 N O = 2.5 So, bond length in N O > N O +
