Chapter 8.2, Problem 15PP

Interpretation Introduction

Interpretation:

The name of the covalent compound ${\text{SO}}_{\text{2}}$ needs to be determined.

Concept introduction:

For the binary covalent compound, there is bond between non metal combined with non metal in the molecular compound.

Answer to Problem 15PP

Sulfur dioxide.

Explanation of Solution

The S is the first the element, both S and O are from the same group thus, highest period number is considered.

The second element is oxygen, only the root word ox is used for the name with suffix ‘ide’ and it has two atoms of oxygen then prefix di is taken.

$\begin{array}{l}{\text{1}}^{\text{st}}{\text{element + Prefix + 2}}^{\text{nd}}\text{element root word + suffix}\hfill \\ \text{Sulfur + di oxide}\hfill \end{array}$

Thus, the name is sulfur dioxide.

Conclusion

The binary covalent compound ${\text{SO}}_2$ name is sulfur dioxide.
