Which of the following pair of compound - boiling point is correct?
I. Chloroform - 334k
II. Methane - 111k
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Both I and II.
I. Chloroform - Chloroform indeed has a boiling point close to 334 K (61.2°C or 142.2°F). It's a volatile liquid commonly used as a solvent.
II. Methane - Methane's boiling point is significantly lower than chloroform's. Methane boils at around 111 K (-161.5°C or -258.7°F). It's a gas at room temperature and pressure, commonly known as natural gas.
