The general density of liquid alkanes gradually increases with molecular mass but eventually plateau — Hydrocarbons Chemistry Question
Question
The general density of liquid alkanes gradually increases with molecular mass but eventually plateaus. What is the approximate upper limit for the density of higher alkanes?
Answer: A
💡 Solution & Explanation
Alkane density increases with mass but plateaus at approximately $0.8 \text{ g/cm}^3$, meaning all pure liquid and solid alkanes are strictly lighter than water.
