Chapter 18, Problem 60E

Interpretation Introduction

Interpretation: The Lewis structure of ${\text{AsCl}}_{\text{4}}^{\text{+}}$ and ${\text{AsCl}}_6^{-}$ ions needs to be drawn and the type of reaction for given conversion needs to be identified as acid-base, oxidation-reduction or as follows:

  ${\text{2 AsCl}}_{\text{5(g)}}^{}\stackrel{}{\to }{\text{AsCl}}_{\text{4}}^{}{\text{AsCl}}_{\text{6(s)}}^{}$

Concept Introduction:

Lewis dot structure is the representation which shows the bonding between atoms present in a molecule. It shows lone pairs and bond pairs that exist on each bonded atom. Lewis dot structure is also known as Lewis dot formula or electron dot structure.

The sum of valence electrons must be arranged in such a way that all atoms must get octet configuration (8 electrons).
