Which of the following pair of compound - boiling point is correct?
I. Chloroform - 334K
II. Methane - 111K

Correct option is D

The correct answer is (d) Both I and II.
• The boiling point of chloroform (CHCl₃) is approximately 334K.
• The boiling point of methane (CH₄) is approximately 111K.
Facts to remember:
• Boiling point is the temperature at which a liquid turns into vapor.
• Chloroform is a volatile, colorless liquid used in various industrial applications.
• Methane is a simple hydrocarbon and a major component of natural gas, with a very low boiling point.
