Final answer:
The correct formula for disulfur tetrafluoride is S₂F₄, which is option 1 from the provided choices.
Step-by-step explanation:
The formula for disulfur tetrafluoride is option 1: S₂F₄. This compound name indicates that there are two sulfur atoms and four fluorine atoms. Each sulfur atom in the molecule is bonded to two fluorine atoms, forming the desired compound. The molecular formulas for other compounds, such as sulfur hexafluoride, dinitrogen trioxide, and xenon tetrafluoride follow the pattern of prefix-subscripted elemental symbol, hence the correct representation for disulfur tetrafluoride follows the same pattern, leading to S₂F₄ as the correct formula.
