Nitric oxide (NO) has a bond order of 2.5, whereas the nitrosonium ion (NO+) has a bond order of 3. Which statement correctly compares their bond lengths?
- The bond length of NO+ is the same as that of NO
- The bond length of NO is greater than the bond length of NO+
- The bond length of NO+ is greater than the bond length of NO
- No definite comparison of bond lengths can be made
Correct answer: The bond length of NO is greater than the bond length of NO+
Solution
A higher bond order indicates a stronger bond, which typically results in a shorter bond length. Since NO+ has a bond order of 3 compared to NO's bond order of 2.5, NO+ has a stronger bond and thus a shorter bond length.
