Concept explainers
(a)
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:
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:
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:

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.
(d)

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.
(f)
Interpretation:
