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.
