Methane, ethane, propane, and butane are gases at room temperature, while pentane, hexane, and heptane are liquids. In terms of ldf, why does boiling point of hydrocarbons increase as more carbons are added to the molecule? a) Molar mass increases and boiling point increases because the molecules are heavier and more likely to be liquids b) As the molecules become larger, there are more electrons per molecule, which makes the larger molecules more polarizable and have stronger ldf forces. c) As the molecules become smaller, there are more electrons per molecule, which makes the larger molecules more polarizable and have stronger ldf forces. d) As molar mass decreases, boiling point increases.
