In the above compound, the bond orders of bonds I and II are:

Options

  1. AI < 2 ,   II > 2
  2. BI > 2 ,   II > 2
  3. CI > 2 ,   II < 2
  4. DI < 2 ,   II < 2

Correct answer

A. I < 2 ,   II > 2

Step-by-step solution

Azide ion N 3 - Bond order: I < 2 Bond Order: II > 2 Due to the delocalisation in I double character increase in single bond and II triple bond character decrease in triple bond (double bond character comes).
