Chapter 6, Problem 49E

Interpretation Introduction

(a)

Interpretation:

The formula for the binary molecular compound dinitrogen trioxide is to be stated.

Concept introduction:

A binary molecular compound is composed of two nonmetal elements. The simplest representative particle in a binary molecular compound is a molecule. Generally, the more nonmetallic element is written second in the chemical formula. The general order of the elements in compound which is prescribed by IUPAC is $\text{C,}\text{P,}\text{N,}\text{H,}\text{S,}\text{I,}\text{Br,}\text{Cl,}\text{O,}\text{F}$ and the compounds are to be written according to the above order.

Answer to Problem 49E

The formula for the binary molecular compound dinitrogen trioxide is ${\text{N}}_{\text{2}}{\text{O}}_{\text{3}}$.

Explanation of Solution

In the naming of binary molecular compound, IUPAC suggested that the first element in the compound to be named is followed by the second element bearing the suffix $-ide$. It also suggested that the number of atoms of each element is indicated by Greek prefixes. In compound dinitrogen trioxide, the ratio is two nitrogen atoms to three oxygen atoms. The suffix $-ide$ is used for oxygen. Therefore, the formula for the compound dinitrogen trioxide is ${\text{N}}_{\text{2}}{\text{O}}_{\text{3}}$.

Conclusion

The formula for the binary molecular compound dinitrogen trioxide is ${\text{N}}_{\text{2}}{\text{O}}_{\text{3}}$.

Interpretation Introduction

(b)

Interpretation:

The formula for the binary molecular compound carbon tetrachloride is to be stated.

Concept introduction:

A binary molecular compound is composed of two nonmetal elements. The simplest representative particle in a binary molecular compound is a molecule. Generally, the more nonmetallic element is written second in the chemical formula. The general order of the elements in compound which is prescribed by IUPAC is $\text{C,}\text{P,}\text{N,}\text{H,}\text{S,}\text{I,}\text{Br,}\text{Cl,}\text{O,}\text{F}$ and the compounds are to be written according to the above order.

Answer to Problem 49E

The formula for the binary molecular compound carbon tetrachloride is ${\text{CCl}}_4$.

Explanation of Solution

In the naming of binary molecular compound, IUPAC suggested that the first element in the compound to be named is followed by the second element bearing the suffix $-ide$. It also suggested that the number of atoms of each element is indicated by Greek prefixes. In compound carbon tetrachloride, the ratio of atoms is one carbon atom to four chlorine atoms. The suffix $-ide$ is used for chlorine. Therefore, the formula for the compound carbon tetrachloride is ${\text{CCl}}_4$.

Conclusion

The formula for the binary molecular compound carbon tetrachloride is ${\text{CCl}}_4$.

Interpretation Introduction

(c)

Interpretation:

The formula for the binary molecular compound iodine monobromide is to be stated.

Concept introduction:

A binary molecular compound is composed of two nonmetal elements. The simplest representative particle in a binary molecular compound is a molecule. Generally, the more nonmetallic element is written second in the chemical formula. The general order of the elements in compound which is prescribed by IUPAC is $\text{C,}\text{P,}\text{N,}\text{H,}\text{S,}\text{I,}\text{Br,}\text{Cl,}\text{O,}\text{F}$ and the compounds are to be written according to the above order.

Answer to Problem 49E

The formula for binary molecular compound iodine monobromide is $\text{IBr}$.

Explanation of Solution

In the naming of binary molecular compound, IUPAC suggested that the first element in the compound to be named is followed by the second element bearing the suffix $-ide$. It also suggested that the number of atoms of each element is indicated by Greek prefixes. In the compound iodine monobromide, the ratio of atoms is one iodine atom to one bromine atom. The suffix $-ide$ is used for bromine. Therefore, the formula for the compound iodine monobromide is $\text{IBr}$.

Conclusion

The formula for binary molecular compound iodine monobromide is $\text{IBr}$.

Interpretation Introduction

(d)

Interpretation:

The formula for the binary molecular compound dihydrogen sulfide is to be stated.

Concept introduction:

A binary molecular compound is composed of two nonmetal elements. The simplest representative particle in a binary molecular compound is a molecule. Generally, the more nonmetallic element is written second in the chemical formula. The general order of the elements in compound which is prescribed by IUPAC is $\text{C,}\text{P,}\text{N,}\text{H,}\text{S,}\text{I,}\text{Br,}\text{Cl,}\text{O,}\text{F}$ and the compounds are to be written according to the above order.

Answer to Problem 49E

The formula for binary molecular compound dihydrogen sulfide is ${\text{H}}_2\text{S}$.

Explanation of Solution

In the naming of binary molecular compound, IUPAC suggested that the first element in the compound to be named is followed by the second element bearing the suffix $-ide$. It also suggested that the number of atoms of each element is indicated by Greek prefixes. In compound dihydrogen sulfide, the ratio of atoms is two hydrogen atoms to one sulfur atom. The suffix $-ide$ is used for sulfur. Therefore, the formula for the compound carbon tetrachloride is ${\text{CCl}}_4$.

Conclusion

The formula for binary molecular compound dihydrogen sulfide is ${\text{H}}_2\text{S}$.
