Question

How do the boiling points of butane, propane, and ethane compare?
Options
A the boiling point of ethane is greatest.
B the boiling point of butane is greatest.
Correct Answer
C the boiling point of propane is greatest.
D there is no relationship among these three alkanes and their boiling points.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Boiling points increase with molecular weight. Butane (C4H10) has the highest molecular weight, followed by propane (C3H8), then ethane (C2H6). Therefore, butane has the highest boiling point.

Hint

How does boiling point vary with molecular weight?
