Question

Which statement is false?
Options
A Many alkanes are soluble in water.
Correct Answer
B All alkanes have a lower density than water.
C At room temperature some alkanes are liquids, some solids, some gases.
D All alkanes burn.
Correct Answer

Option A is the correct answer.

Detailed Explanation

Alkanes are nonpolar and insoluble in water. They are not soluble in water. The other statements are true: alkanes are less dense than water (float), physical states vary with molecular weight (C1-C4 gases, C5-C17 liquids, C18+ solids), and all alkanes are combustible.

Hint

Are alkanes polar or nonpolar?
