Which of the following best represents the freezing point of fluorine (F_2) under standard atmospheric pressure?

• A. -101.0 ^ext{o}C
• B. 0 ^ext{o}C
• C. -182.5 ^ext{o}C
• D. -219.6 ^ext{o}C

Answer: (D)

Verified step by step guidance

1. Understand that the freezing point of a substance is the temperature at which it changes from liquid to solid under standard atmospheric pressure.
2. Recall or look up the physical properties of fluorine (F_2), specifically its freezing point under 1 atm pressure.
3. Note that fluorine is a diatomic halogen gas at room temperature and has very low freezing and boiling points due to weak intermolecular forces (London dispersion forces).
4. Compare the given options with the known freezing point of fluorine, which is approximately -219.6 \^\{\text{o}\}C, indicating it freezes at a very low temperature.
5. Conclude that among the options, -219.6 \^\{\text{o}\}C best represents the freezing point of fluorine under standard atmospheric pressure.
