Question

please complete the following table:

1. carbon dioxide
2. phosphorus triiodide
3. sulfur dichloride
4. nitrogen trifluoride
5. dioxygen difluoride
6. n₂f₄
7. scl₄
8. clf₃
9. sio₂
10. p₄o₁₀

Explanation:

Step1: Recall naming rules for covalent compounds

Prefixes (di - 2, tri - 3, tetra - 4, etc.) are used to indicate the number of atoms of each element in the formula.

Step2: Determine formulas for given names

• Carbon dioxide: “di” means 2. So formula is \(CO_{2}\)
• Phosphorus triiodide: “tri” means 3. Formula is \(PI_{3}\)
• Sulfur dichloride: “di” means 2. Formula is \(SCl_{2}\)
• Nitrogen trifluoride: “tri” means 3. Formula is \(NF_{3}\)
• Dioxygen difluoride: “di” (for oxygen) and “di” (for fluorine). Formula is \(O_{2}F_{2}\)

Step3: Determine names for given formulas

• \(N_{2}F_{4}\): “di” (for nitrogen) and “tetra” (for fluorine). Name is dinitrogen tetrafluoride
• \(SCl_{4}\): “tetra” (for chlorine). Name is sulfur tetrachloride
• \(ClF_{3}\): “tri” (for fluorine). Name is chlorine trifluoride
• \(SiO_{2}\): “di” (for oxygen). Name is silicon dioxide
• \(P_{4}O_{10}\): “tetra” (for phosphorus) and “deca” (10, for oxygen). Name is tetraphosphorus decoxide

Answer:

Name of Covalent Compound	Formula of Covalent Compound
2. phosphorus triiodide	\(PI_{3}\)
3. sulfur dichloride	\(SCl_{2}\)
4. nitrogen trifluoride	\(NF_{3}\)
5. dioxygen difluoride	\(O_{2}F_{2}\)
6. dinitrogen tetrafluoride	\(N_{2}F_{4}\)
7. sulfur tetrachloride	\(SCl_{4}\)
8. chlorine trifluoride	\(ClF_{3}\)
9. silicon dioxide	\(SiO_{2}\)
10. tetraphosphorus decoxide	\(P_{4}O_{10}\)
