Chapter 21.3, Problem 4PE

Interpretation Introduction

Interpretation: The lewis structure of ${\text{NO}}_{\text{2}}$ and ${\text{NO}}_{\text{2}}{}^{-}$ is to be drawn and prediction about their same molecular geometry about nitrogen is to be done. The hybrid orbitals that contain nitrogen lone pairs are to be identified.

Concept introduction: The Lewis structures are diagrams that give information about the bonding electron pairs and the lone pairs of electrons in a molecule. They are similar to electron dot structure.

To determine: The lewis structure of ${\text{NO}}_{\text{2}}$ and ${\text{NO}}_{\text{2}}{}^{-}$, if they have molecular geometry about nitrogen and hybrid orbitals that contain nitrogen lone pairs.
