Chapter 8, Problem 94A

Interpretation Introduction

(a)

Interpretation:

The name of the molecule ${\text{SeO}}_2$ needs to be given.

Concept introduction:

A binary compound comprises of two nonmetal atoms. For naming this compound, first write the name of first element, then second element formula is named by using its root and adding suffix-ide. Prefix is used to identify the atom’s number in each element.

Answer to Problem 94A

The common name of the ${\text{SeO}}_2$ is selenium dioxide.

Explanation of Solution

The first element of this molecule is Se, so, its name is written first. The symbol Se represents selenium.

The second element is oxygen and it is named by its root −ox by adding −ide. In this molecule number of Se is one and O is 2. So, prefix di is used. Hence, the name of the molecule is selenium dioxide.

Interpretation Introduction

(b)

Interpretation:

The name of the molecule ${\text{SeO}}_3$ needs to be given.

Concept introduction:

A binary compound comprises of two nonmetal atoms. For naming this compound, first write the name of first element, then second element formula is named by using its root and adding suffix-ide. Prefix is used to identify the atom’s number in each element.

Answer to Problem 94A

The name of the ${\text{SeO}}_3$ is selenium trioxide.

Explanation of Solution

The first element of this molecule is Se, so, its name is written first. The symbol Se represents selenium.

The second element is oxygen and it is named by its root −ox by adding −ide. In this molecule number of Se is one and O is 3. So, prefix tri is used in front of O. Hence, the name of the molecule is selenium trioxide.

Interpretation Introduction

(c)

Interpretation:

The name of the molecule ${\text{N}}_{\text{2}}{\text{F}}_{\text{4}}$ needs to be given.

Concept introduction:

A binary compound comprises of two nonmetal atoms. For naming this compound, first write the name of first element, then second element formula is named by using its root and adding suffix-ide. Prefix is used to identify the atom’s number in each element.

Answer to Problem 94A

The common name of the ${\text{N}}_{\text{2}}{\text{F}}_{\text{4}}$ is dinitrogen tetrafluoride.

Explanation of Solution

The first element of this molecule is N, so, its name is written first. The symbol N represents Nitrogen.

The second element is fluoride and it is named by its root with adding −ide. Here, number of nitrogen is 2 and fluoride is 4. So, di and tetra is used as prefix in front of N and F respectively. Hence, the name of the molecule is dinitrogen tetrafluoride.

Interpretation Introduction

(d)

Interpretation:

The name of the molecule ${\text{S}}_4{\text{N}}_4$ needs to be given.

Concept introduction:

A binary compound comprises of two nonmetal atoms. For naming this compound, first write the name of first element, then second element formula is named by using its root and adding suffix-ide. Prefix is used to identify the atom’s number in each element.

Answer to Problem 94A

The common name of the ${\text{S}}_4{\text{N}}_4$ is tetrasulfur tetranitride.

Explanation of Solution

The first element of this molecule is S, so, its name is written first. The symbol S represents Sulfur.

The second element is N and it is named by its root with adding −ide. Number of S and N is four. So, tetra prefix is used. Hence, the name of the molecule is tetrasulfur tetranitride.
