Chapter 9, Problem 100A

(a)

Interpretation Introduction

Interpretation: The compounds are to be separated into five categories or more than one category.

Concept Introduction : Molecular compounds are formed by the sharing of electrons between non-metals. They are known as carbon compounds.

Ionic compounds are formed by the transfer of electrons between metal and non-metal.

Polyatomic ions are ions that have more than one atom. While naming polyatomic ions, the name of the less electronegative element is placed first, followed by the higher electronegative element. ‘−ate’ or ‘-ite’ is used as a suffix for anions.

Answer to Problem 100A

It is binary molecular compound.

Explanation of Solution

The given compound is ${\text{CBr}}_{\text{4}}$ . It is composed of two non-metals. Thus, it is binary molecular compound.
