Phosphorus trichloride
Explanation
The names of the given compounds are determined using the prefix-based naming conventions for binary covalent compounds illustrated in the text. CO₂ is named carbon dioxide as it contains two oxygen atoms. Similarly, NO₂ is named nitrogen dioxide, applying the 'di' prefix for two oxygen atoms. SF₆ is named sulfur hexafluoride because it contains six fluorine atoms. PCl₃ is named phosphorus trichloride as it has three chlorine atoms.
