Chapter 4, Problem 40P

(a)

Interpretation Introduction

Interpretation:

Formula for the covalent compound carbon disulfide should be determined.

Concept Introduction:

In covalent compounds, prefixes are used to indicate the number of atoms of each element present in the compound. The most negative element is end with suffix -ide.

The prefixes used are as follows:

1	mono-
2	di-
3	tri-
4	tetra-
5	penta-
6	hexa-

Generally, mono is not used in the formula for the first element. When they are attached to oxygen (oxide), the ‘o’ and ‘a’ ending of prefixes are not used.

(b)

Interpretation Introduction

Interpretation:

Formula for the covalent compound chlorine trifluoride should be determined.

Concept Introduction:

In covalent compounds, prefixes are used to indicate the number of atoms of each element present in the compound. The most negative element is end with suffix -ide.

The prefixes used are as follows:

1	mono-
2	di-
3	tri-
4	tetra-
5	penta-
6	hexa-

Generally, mono is not used in the formula for the first element. When they are attached to oxygen (oxide), the ‘o’ and ‘a’ ending of prefixes are not used.

(c)

Interpretation Introduction

Interpretation:

Name for the covalent compound PF₅ should be determined.

Concept Introduction:

In covalent compounds, prefixes are used to indicate the number of atoms of each element present in the compound. The most negative element is end with suffix -ide.

The prefixes used are as follows:

2	di-
3	tri-
4	tetra-
5	penta-
6	hexa-

Generally, mono is not used in the formula for the first element. When they are attached to oxygen (oxide), the ‘o’ and ‘a’ ending of prefixes are not used.
