Final answer:
The correct option is B) Carbon tetrachloride (CCl4), which correctly matches the compound's formula. The other listed compounds are either named incorrectly or don't match common chemical naming conventions and their respective formulas.
Step-by-step explanation:
Among the options provided, the compound that is named correctly is B) Carbon tetrachloride (CCl4). The proper names and formulas for the other examples, based on the prefixes and the elements involved, are as follows:
- Germanium dioxide: GeO2
- Carbon disulfide: CS2
- Phosphorus pentachloride: PCl5
- Dinitrogen monoxide: N2O
- Iodine heptafluoride: IF7
- Nitrogen triiodide: NI3
- Dioxygen dichloride: O2Cl2
- Dinitrogen trisulfide: N2S3
- Xenon tetrafluoride: XeF4
- Calcium chloride: CaCl2
- Aluminum fluoride: AlF3
- Potassium chloride: KCl
- Silicon dioxide: SiO2
As we can see, the correct naming convention of ionic and covalent compounds involves using the right prefixes (mono-, di-, tri-, tetra-, etc.) to indicate the number of atoms and understanding the elements that constitute the compound.
