Classify each compound as ionic or molecular:

a .  CO b .  ZnBr 2 c .  CH 4 d .  NaF  

Interpretation Introduction

Interpretation:

Each of the following given compounds is to be classified as ionic or molecular compound.

Concept introduction:

Molecular compounds contain only nonmetals that are covalently bonded to each other. Any compound that has atleast two different elements is considered to be a molecule.

Ionic compounds contain atoms of metals and nonmetals that are bonded together by ionic bonds formed via the transfer of electrons between the atoms.

Explanation of Solution

a) CO

CO, carbon monoxide, is a molecular compound that consists of two nonmetals bonded together by a covalent bond, which is formed by the sharing of valence electrons of the outermost shell of atoms. A covalent bond is relatively weaker than an ionic bond.

b) ZnBr2

ZnBr2, zinc bromide, is an ionic compound that consists of metal and nonmetal elements bonded together via ionic bonds, which are formed as a result of electron transfer between the ions. Here, the metal acts as the cation (Zn2+) and the nonmetal acts as the anion (Br). An ionic bond is comparatively much stronger than a covalent bond
