Explanation:

Step1: Recall naming rules for molecular compounds

Prefixes are used to indicate the number of atoms of each element.

Step2: Name CBr₄

The prefix for 1 carbon is "mono -" (usually omitted for the first element), and for 4 bromine is "tetra -". So it is carbon tetrabromide.

Step3: Check formula for trisulfur octafluoride

The correct formula for trisulfur octafluoride is S₃F₈, not P₂H₆.

Step4: Name the compound for P₂H₆

There is no common name for P₂H₆ following the simple molecular - compound naming rules. It could be diphosphorus hexahydride.

Step5: Check formula for tetracarbon decahydride

The correct formula for tetracarbon decahydride is C₄H₁₀, not C₂H₆.

Step6: Name the compound for C₂H₆

C₂H₆ is ethane.

Step7: Check formula for dihydrogen monoxide

The correct formula for dihydrogen monoxide is H₂O, not C₄F₁₀.

Step8: Name the compound for C₄F₁₀

It is tetracarbon decafluoride.

Step9: Check formula for methane

The correct formula for methane is CH₄, not N₂O₄.

Step10: Name the compound for N₂O₄

It is dinitrogen tetroxide.

Step11: Name the compound for P₂I₄

It is diphosphorus tetraiodide.

Step12: Check formula for heptasulfur noniodide

The correct formula for heptasulfur noniodide is S₇I₉.

Step13: Name the compound for S₆Clₓ (assuming x is the correct number of chlorine atoms)

If we assume the correct formula is S₆Cl₆, it is hexasulfur hexachloride.

Step14: Check formula for pentaboron hexaselenide

The correct formula for pentaboron hexaselenide is B₅Se₆.

Step15: Name the compound for C₂O₂

It is dicarbon dioxide (also known as oxalyl).

6. Tetracarbon decafluoride (C₄F₁₀)
7. N/A (wrong formula for methane)
8. Dinitrogen tetroxide (N₂O₄)
9. Diphosphorus tetraiodide (P₂I₄)
10. N/A (wrong formula for heptasulfur noniodide)
11. N/A (assuming wrong formula S₆Clₓ)
12. N/A (wrong formula for pentaboron hexaselenide)
13. N/A (assuming wrong formula C₂O₂ for heptasilicon monosulfide)
14. N/A (assuming wrong formula for heptasilicon monosulfide)
15. Dicarbon dioxide (C₂O₂)
