Chapter 8, Problem 93A

Interpretation Introduction

(a)

Interpretation:

The name of the molecule ${\text{NF}}_{\text{3}}$ 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 93A

The common name of the ${\text{NF}}_{\text{3}}$ is nitrogen trifluoride.

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 fluorine and it is named by its root by adding −ide. Hence, the name of the molecule is nitrogen trifluoride.

Interpretation Introduction

(b)

Interpretation:

The name of the molecule $\text{NO}$ 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 93A

The common name of the $\text{NO}$ is nitrogen monoxide.

Explanation of Solution

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

The second element is oxygen and it is named by its root with adding −ide. Here, number of N is one and O is one, mono is used as prefix. Hence, the name of the molecule is nitrogen monoxide.

Interpretation Introduction

(c)

Interpretation:

The name of the molecule ${\text{SO}}_3$ 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 93A

The common name of the ${\text{SO}}_3$ is sulfur trioxide.

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 oxygen and it is named by its root with adding −ide. Prefix tri is used as number of oxygen is 3. Hence, the name of the molecule is Sulfur trioxide.

Interpretation Introduction

(c)

Interpretation:

The name of the molecule ${\text{SiF}}_4$ 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 atoms number in each element.

Answer to Problem 93A

The common name of the ${\text{SiF}}_4$ is silicon tetrafluoride.

Explanation of Solution

The first element of this molecule is Si, so, its name is written first. The symbol Si represents silicon.

The second element is oxygen and it is named by its root with adding −ide. Prefix tetra is used as number of F is 4. Hence, the name of the molecule is silicon tetrafluoride.
