Final answer:
The molecular compounds IF₃, P₂O₅, SiO₂, PCl₃, and CO are named iodine trifluoride, diphosphorus pentoxide, silicon dioxide, phosphorus trichloride, and carbon monoxide, respectively, following the systematic approach for naming covalent compounds.
Step-by-step explanation:
Naming molecular compounds involves using prefixes to indicate the number of atoms of each element and adding the appropriate suffix to the name of the second element to indicate that it is part of a compound. Here are the names of the given compounds:
- IF₃ is named iodine trifluoride.
- P₂O₅ is called diphosphorus pentoxide.
- SiO₂ is known as silicon dioxide.
- PCl₃ is called phosphorus trichloride.
- CO is named carbon monoxide.
These names are based on a systematic approach to naming covalent compounds, where the first element is named first using the full element name, and the second element is named as if it were an anion with the 'ide' suffix, along with prefixes such as mono-, di-, tri-, tetra-, penta-, etc., to denote the number of atoms present if there is more than one.
