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 |
| :---------------- | :--------------- |
| $CO _2$ | |
| $Br _2 O$ | |
| CO | |
| $BrO _2$ | |
| $H _2 O$ | |
Answer (1)
C O 2 is carbon dioxide.
B r 2 O is dibromine monoxide.
CO is carbon monoxide.
B r O 2 is bromine dioxide.
H 2 O is water.
The final answers are:
C O 2 : carbon dioxide B r 2 O : dibromine monoxide CO : carbon monoxide B r O 2 : bromine dioxide H 2 O : water
b o x e d C O 2 : carbon dioxide b o x e d B r 2 O : dibromine monoxide b o x e d CO : carbon monoxide b o x e d B r O 2 : bromine dioxide b o x e d H 2 O : water
Explanation
Problem Analysis We need to determine the systematic names for the given chemical compounds: C O 2 , B r 2 O , CO , B r O 2 , and H 2 O . For compounds containing hydrogen, we can use the common name.
Naming C O 2 C O 2 is composed of one carbon atom and two oxygen atoms. The systematic name is carbon dioxide.
Naming B r 2 O B r 2 O is composed of two bromine atoms and one oxygen atom. The systematic name is dibromine monoxide.
Naming CO CO is composed of one carbon atom and one oxygen atom. The systematic name is carbon monoxide.
Naming B r O 2 B r O 2 is composed of one bromine atom and two oxygen atoms. The systematic name is bromine dioxide.
Naming H 2 O H 2 O is composed of two hydrogen atoms and one oxygen atom. The common name is water.
Final Answer The systematic names of the chemical compounds are:
C O 2 : carbon dioxide B r 2 O : dibromine monoxide CO : carbon monoxide B r O 2 : bromine dioxide H 2 O : water
Examples
Understanding chemical nomenclature is crucial in various fields, such as environmental science, where identifying pollutants like carbon monoxide (CO) and carbon dioxide ( C O 2 ) is essential for monitoring air quality and assessing the impact of industrial emissions. Similarly, in medicine, knowing the composition and names of chemical compounds helps in understanding drug interactions and their effects on the human body. For instance, water ( H 2 O ) is fundamental for all biological processes, and its properties are vital in understanding physiological functions. The ability to name and recognize chemical compounds allows scientists and professionals to communicate effectively and accurately about chemical substances.
