Which of the following is the correct chemical formula for disulfur decafluoride?

• A. S2F6
• B. SF10
• C. S2F10
• D. SF6

Answer: (C)

Verified step by step guidance

1. Step 1: Understand the naming convention for covalent compounds, which often use prefixes to indicate the number of atoms of each element in the molecule. 'Di-' means 2, and 'deca-' means 10.
2. Step 2: Identify the elements involved from the name 'disulfur decafluoride'. 'Disulfur' indicates 2 sulfur (S) atoms, and 'decafluoride' indicates 10 fluorine (F) atoms.
3. Step 3: Write the chemical formula by placing the symbols of the elements with their respective quantities as subscripts: \(\mathrm{S_2F_{10}}\).
4. Step 4: Verify that the formula matches the naming: 2 sulfur atoms and 10 fluorine atoms correspond to 'disulfur decafluoride'.
5. Step 5: Compare the options given and select the formula that matches \(\mathrm{S_2F_{10}}\) as the correct chemical formula.
