B) that n-hexane is more dense than water
C) that these two compounds have the same density
D) that the relative densities of two immiscible compounds cannot be measured

Question

Quizplus · Accepted Answer

n-hexane is less dense than water. This is because n-hexane is a hydrocarbon with a relatively simple structure and lower molecular weight compared to water, which is a polar molecule with hydrogen bonding. Therefore, n-hexane molecules are less tightly packed than water molecules, resulting in a lower density.
