Chapter 9, Problem 40E

Interpretation Introduction

Interpretation:

The compound with stronger nitrogen-nitrogen bond and shorter nitrogen-nitrogen bond length from the given compounds hydrazine $\left({\text{H}}_{\text{2}}{\text{NNH}}_{\text{2}}\right)$ and dinitrogen dihydride $\left(\text{HNNH}\right)$ is to be identified.

Concept introduction: The strength and length of a bond formed between two atoms depends on the type of bond formed between them. Normally three types of covalent bonds are formed between atoms; these are single, double and triple bond. The increasing order of bond strengths of single, double and triple bond is,

$\text{Single}\text{bond}<\text{Double}\text{bond}<\text{Triple}\text{bond}$

To determine: The compound with stronger nitrogen-nitrogen bond and shorter nitrogen-nitrogen bond length from the given compounds hydrazine $\left({\text{H}}_{\text{2}}{\text{NNH}}_{\text{2}}\right)$ and dinitrogen dihydride $\left(\text{HNNH}\right)$
