Which of the following is the correct chemical formula for dioxygen difluoride?

• A. O2F
• B. O2F2
• C. F2O2
• D. OF2

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the name 'dioxygen difluoride'. The prefix 'di-' means two atoms of the element it precedes. So 'dioxygen' means 2 oxygen atoms, and 'difluoride' means 2 fluorine atoms.
2. Step 2: Write down the number of atoms for each element based on the prefixes: oxygen (O) = 2 atoms, fluorine (F) = 2 atoms.
3. Step 3: Combine the atoms to form the chemical formula by placing the element symbols followed by their respective numbers: O2 and F2.
4. Step 4: Write the formula as O2F2, which represents two oxygen atoms and two fluorine atoms bonded together.
5. Step 5: Verify that the formula matches the naming convention and the options given; O2F2 correctly corresponds to dioxygen difluoride.
