Textbook Problem

Compare the nitrogen-nitrogen bond in hydrazine, H2NNH2, with that in “laughing gas,” N2O. In which molecule is the nitrogen-nitrogen bond shorter? In which is the bond stronger?

Interpretation Introduction

Interpretation: The Nitrogen – Nitrogen bond in Hydrazine and in N2O should be compared and the molecule with stronger and shorter nitrogen–nitrogen bond should be identified.

Concept Introduction:

The bond order gives an idea about the stability of a molecule. It can be calculated using the molecular orbital theory. The stability of a molecule increase as the bond order increases. The bond order for any bonded pair atoms, like X and Y determined as follows,

  Bondorder=No. of shared pairs in all X-Y bondsNo. of X-Y links in the molecule or ion

Explanation

The Lewis structure of hydrazine and N2O are as follows,

    

The nitrogen–nitrogen bond in hydrazine is a single bond, while in
