Chapter 6, Problem 6.81AQAP

(a)

Interpretation Introduction

Interpretation:

The compound ${\text{FeCl}}_{\text{3}}$ needs to be identified as ionic or molecular.

Concept Introduction:

Ionic compounds are formed by the transfer of electrons from one atom to other this is due to the strong electrostatic forces of attraction existing between the atoms of different elements. This strong electrostatic force of attraction results in the formation of ionic bonds between the two atoms. They are generally formed between metals and non-metals with electronegativity difference. Molecular compounds are those compounds which are formed between the two atoms by sharing of electrons. They are generally formed between two non-metals.

Interpretation Introduction

(b)

Interpretation:
