(a) Interpretation: Two other resonance structures for hydrazoic acid (N 3 H) need to be drawn. Concept introduction: A Lewis dot structure depicts bonding between atoms in a molecule in terms of the valence electrons, bonding electron pairs as well as the lone pairs surrounding individual atoms. If a molecule can be represented by more than one Lewis structure then the contributing forms which represent electron delocalization are termed as resonance structures.

Question

Chapter 7, Problem 23QAP

Interpretation Introduction

(a)

Interpretation:

Two other resonance structures for hydrazoic acid (N₃ H) need to be drawn.

Concept introduction:

A Lewis dot structure depicts bonding between atoms in a molecule in terms of the valence electrons, bonding electron pairs as well as the lone pairs surrounding individual atoms.

If a molecule can be represented by more than one Lewis structure then the contributing forms which represent electron delocalization are termed as resonance structures.

Interpretation Introduction

(b)

Interpretation:

An explanation must be provided if the depicted structure of hydrazoic acid contributes to its resonance form.

Concept introduction:

A Lewis dot structure depicts bonding between atoms in a molecule in terms of the valence electrons, bonding electron pairs as well as the lone pairs surrounding individual atoms.

If a molecule can be represented by more than one Lewis structure then the contributing forms which represent electron delocalization are termed as resonance structures.
