Chapter 8, Problem 80A

Interpretation Introduction

Interpretation: The similarity between elements that form covalent bonds from the compounds in table 8.2 needs to be determined.

Concept Introduction: Covalent compounds are formed by sharing of electron pairs between two atoms of the same or different elements. The bond formed between two atoms by sharing of electrons is known covalent bond. It is generally formed between two non-metals.

Explanation of Solution

The compounds given in table 8.2 are as follows:

Carbon monoxide $\text{CO}$ , Carbon dioxide ${\text{CO}}_2$ , Hydrogen peroxide ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$ , Sulfur dioxide ${\text{SO}}_{\text{2}}$ , Sulfur trioxide ${\text{SO}}_3$ , Nitric oxide $\text{NO}$ , Nitrogen dioxide ${\text{NO}}_2$ , Dinitrogen tetroxide ${\text{N}}_2{\text{O}}_4$ , Nitrous oxide ${\text{N}}_{\text{2}}\text{O}$ , Hydrogen cyanide $\text{HCN}$ , Hydrogen fluoride $\text{HF}$ , Hydrogen chloride $\text{HCl}$ , Hydrogen bromide $\text{HBr}$ , Hydrogen iodide $\text{HI}$ .

From table 8.2, the elements found in the compounds are as follows:

Carbon

Oxygen

Hydrogen

Sulfur

Nitrogen

Fluorine

Chlorine

Bromine

Iodine

Here, all the elements can form covalent compounds by sharing electrons with an atom of the same or different elements. Here, the similarity between the two elements is that they are non-metals.
