Fill in the systematic names of the following chemical compounds. Note: for compounds containing hydrogen, you may give the common name instead.
| molecular formula | name of compound |
|---|---|
| [tex]$Cl _2 O _3$[/tex] | |
| [tex]$PCl _3$[/tex] | |
| [tex]$PCl _5$[/tex] | |
| [tex]$Cl _2 O _7$[/tex] | |
| [tex]$H _2 O$[/tex] | |
Answer (1)
C l 2 O 3 is dichlorine trioxide.
PC l 3 is phosphorus trichloride.
PC l 5 is phosphorus pentachloride.
C l 2 O 7 is dichlorine heptoxide.
H 2 O is water.
The systematic names of the chemical compounds are d i c h l or in e t r i o x i d e , p h os p h or u s t r i c h l or i d e , p h os p h or u s p e n t a c h l or i d e , d i c h l or in e h e pt o x i d e , w a t er .
Explanation
Problem Analysis We need to determine the systematic names for the given chemical compounds based on their molecular formulas. For H 2 O , we can provide the common name.
Dichlorine Trioxide C l 2 O 3 is dichlorine trioxide.
Phosphorus Trichloride PC l 3 is phosphorus trichloride.
Phosphorus Pentachloride PC l 5 is phosphorus pentachloride.
Dichlorine Heptoxide C l 2 O 7 is dichlorine heptoxide.
Water H 2 O is water.
Final Answer The systematic names of the chemical compounds are:
C l 2 O 3 : dichlorine trioxide PC l 3 : phosphorus trichloride PC l 5 : phosphorus pentachloride C l 2 O 7 : dichlorine heptoxide H 2 O : water
Examples
Understanding chemical nomenclature is essential in various fields, such as medicine, environmental science, and materials science. For instance, in medicine, knowing the precise chemical composition of drugs is crucial for dosage and potential side effects. In environmental science, identifying pollutants by their chemical names helps in assessing their impact on ecosystems. In materials science, the properties of new materials are often linked to their chemical structure and composition. By learning to name chemical compounds systematically, you gain a fundamental skill that supports further studies and practical applications in these diverse areas.
