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 |
| :---------------- | :--------------- |
| $N _2 F_4$ | |
| $NF _3$ | |
| $P _4 S_3$ | |
| $P _4 S_7$ | |
| $H _2 O$ | |
Answer (2)
N 2 F 4 is named dinitrogen tetrafluoride.
N F 3 is named nitrogen trifluoride.
P 4 S 3 is named tetraphosphorus trisulfide.
P 4 S 7 is named tetraphosphorus heptasulfide.
H 2 O is commonly known as water.
The final answers are: N 2 F 4 : dinitrogen tetrafluoride, N F 3 : nitrogen trifluoride, P 4 S 3 : tetraphosphorus trisulfide, P 4 S 7 : tetraphosphorus heptasulfide, H 2 O : water. N 2 F 4 : dinitrogen tetrafluoride , N F 3 : nitrogen trifluoride , P 4 S 3 : tetraphosphorus trisulfide , P 4 S 7 : tetraphosphorus heptasulfide , H 2 O : water
Explanation
Problem Analysis We need to determine the names of the given chemical compounds based on their molecular formulas. For compounds containing hydrogen, we can use the common name.
Dinitrogen Tetrafluoride N 2 F 4 : This compound consists of two nitrogen atoms and four fluorine atoms. The systematic name is dinitrogen tetrafluoride.
Nitrogen Trifluoride N F 3 : This compound consists of one nitrogen atom and three fluorine atoms. The systematic name is nitrogen trifluoride.
Tetraphosphorus Trisulfide P 4 S 3 : This compound consists of four phosphorus atoms and three sulfur atoms. The systematic name is tetraphosphorus trisulfide.
Tetraphosphorus Heptasulfide P 4 S 7 : This compound consists of four phosphorus atoms and seven sulfur atoms. The systematic name is tetraphosphorus heptasulfide.
Water H 2 O : This compound consists of two hydrogen atoms and one oxygen atom. The common name is water.
Final Answer The systematic or common names of the compounds are:
N 2 F 4 : dinitrogen tetrafluoride
N F 3 : nitrogen trifluoride
P 4 S 3 : tetraphosphorus trisulfide
P 4 S 7 : tetraphosphorus heptasulfide
H 2 O : water
Examples
Understanding chemical nomenclature is essential in various fields, such as medicine, environmental science, and materials science. For instance, in drug development, accurately naming compounds ensures clear communication and avoids confusion, which is crucial for patient safety. In environmental monitoring, knowing the names of pollutants helps in tracking their sources and effects. In materials science, proper naming aids in the synthesis and characterization of new materials with specific properties. This systematic approach to naming compounds allows scientists to communicate effectively and accurately about the substances they are working with, regardless of their location or background.
The systematic names for the compounds are: N₂F₄: dinitrogen tetrafluoride, NF₃: nitrogen trifluoride, P₄S₃: tetraphosphorus trisulfide, P₄S₇: tetraphosphorus heptasulfide, and H₂O: water.
